NGC 4666 and ASASSN-14LP, a galaxy harboring a supernova – December 21, 2014

Object Name (NGC 4666 and ASASSN-14LP)
Object Type (Galaxy and Supernova)
Location (Observatoire Astronomique de Bauduen – Provence France)
Date (2014 12 21)
Media (graphite pencil, white paper, just rapid usage of Paint.net to invert the B&W)

Here’s the sketch I made while looking at this galaxy. The mag. estimation I did is far better than expected : 11.2.
A target easy to find because the galaxy NGC 4666 is quite big and very close to gamma Virgo with a confortable magnitude, but the SN is very close to the galactic centrum, only 12 sec of arc!!, so to separate the two lights the use of the 24″ helps a lot.

SN 2014J in M82

Galaxy M 82 with Supernova SN2014J on February 4, 2014
Galaxy M 82 with Supernova SN2014J on February 4, 2014

Hello,

Two and a half hours of clear sky at 04.Februar 2014 were sufficient to hold the SN in M82 and take a long walk on the winter night sky.

After a tough cloud cover and then the mist had dissolved about 21:00 clock, I could start the observation with the TMB 115/805 Apo.

The supernova was a really great thing! Very bright and striking beamed the SN in the “cigar”. After a brief enjoyment, I started with the sketch!
Unfortunately, the review was only mediocre, so blurred finer structures of the galaxy almost. Nice to see was the interruption in M 82 and south two light specks.

The Brightest Supernova in My Life

Messier 82 and SN2014J - January 31, 2014
Messier 82 and SN2014J – January 31, 2014

I saw SN2014J in M82 on Korean New Year night.

It is very surprise event to me, since I’ve never seen bright supernova.

Already I saw some supernovas in 2011. (M51, M101, NGC2655)

But that is more dark than this one.

I feel some futility.. because it is too easy to observing 🙂

I drew a sketch with 10″ dob, black paper and white pastel & jelly pen.

And I compared with my previous M82 sketch.

It is so interesting, I want to share everyone!

Object Name (SN 2014J in M82)
Object Type (Supernova in galaxy)
Location (Provence – France)
Date (Feb 2nd 2014)
Media (graphite pencil, watercolour on white paper)

Hello sketchers, here is my contribution to the observation of SN 2014J.

From Jan. 23rd till Feb. 11th I spend a lot of good time with the M82 supernova. Sketching the galaxy, estimate the visual magnitude and made watercolour of the sceneries.
Sometime I observed with friends and their materials, sometime I’m alone on the middle of no where, between the Provencal wild nature and the dark sky. Here in south France the temperature is quite high for the season but wind blows, so, often I place my car to protect the 12” Dobson from the mistral.
Attached is a kind of “auto portrait” (yes, that’s me!), from a photo I take tonight. On the basis I add the AAVSO curve with my own visual observations (blue cross is DMIB).

The technique used is inverted watercolour, so I invert the colours of the sketch while scanning. For the galaxy this is common sketch black on white – inverted.

Thanks to read this, clear sky to you all !

Object Name: M74 and SN2013ej
Object Type: galaxy and supernova
Location: Cherry Springs, Pennsylvania
Date: August 5, 2013
Media: graphite pencil, white paper, digitally inverted and scaled

Notes: 16″ Newtonian, 225x. Observed UT 2013-08-05 06:30-08:20. 10 deg. C, 75% humidity. Exceptional transparency, good seeing. Most of the night the transparency was variable, but it became exceptionally good (at least for summer) one hour before astronomical twilight. As M74 was then reaching respectable altitude, it erupted with detail. The very compact HII region Hodge 627 was seen intermittently within the star cloud at the end of the southern arm. Although the exaggerates this brightness difference, supernova 2013ej was indeed brighter than the surrounding Milky Way stars.

SN 2011fe in Messier 101

Here is a sketch of the unusually bright supernova that appeared last August 24th in the Pinwheel Galaxy (M 101) in Ursa Major. SN 2011fe is now at its maximum around magnitude 10 and it is very easy to see in my 120mm refractor, but it was also easy with an 80mm refractor (I estimated magnitude 10.3 on Sept. 4th and 10.0 on 6th). In contrast, as I am observing with moderate light pollution and M 101 is low, the galaxy itself is barely visible and I only can see the central region with effort. SN 2011fe is a nearby type Ia supernova and the brightest one since 1987. 2011 is being a great year for supernova observers!

A 25 Million Year Old Announcement

Last week the supernova SN 2011dh in M 51 galaxy was near its maximum brightness around magnitude 12.3 and I was able to observe it with my 120mm refractor. The two famous interacting galaxies are very well placed in the sky these days. At the eyepiece, the main galaxy has a bright central region and a big, oval halo; the satellite galaxy has a nearly as bright core but a small and round halo. I needed 77x to spot the supernova in the southeast rim of the main galaxy, although the best view of it was at 149x. At this magnification the supernova was easily visible next to a fainter star. The sketch is a composite of both magnifications. It was remarkable that the supernova was visible even in late twilight conditions. SN 2011dh is a type IIb supernova that resulted from the explosion of a supergiant star with 18-22 solar masses, at a distance of 25 million light years. What a sight!

Stellar Explosion in The Whirlpool

Object : Supernova SN2011dh in Spiral Galaxy M51
Date : June 08, 2011
Time : 12:30-02:00 LST/ 07:30-09:00 UT
Location : Aguila, Arizona USA
Gear : Binoculars 25 x 100 and CPC1100 XLT with 25mm Plossl
Detector : Visual Sketch
Magnitude : 8.5 for M51 and 14.9 for SN2011dh(webtreatz.com)
Weather : Clear sky, no winds, low 70’s and quiet as a mouse!
Comments :
It’s interesting to ponder in awe, how a star that has turned into a supernova some 30 million light years distant is just NOW reaching our immediate universe, our light buckets our dilated pupils! This recently discovered supernova cataloged SN2011dh and found on May 31, 2011, might not last long. It’s believed to be diminishing in magnitude with a possible viewing window of some weeks or perhaps a couple of months. If you would like to get a glimpse of it, my suggestion is- don’t wait any longer!
With mounted binoculars it is quite easy to pick up M51 as it appears elongated and fuzzy. Some fidgetting of the eyeball around the circumference of the oculars and it’s companion NGC5195 emerges just as well. Both gravitationally interacting galaxies seem like puffs of smoke with their nucleus showing a hint of brightness.There are no noticeable spiral arms, no connecting bridge or other discernable features- not even the main attraction SN2011dh.
All this will change when I prepare the 11 inch SCT and aim it at the said subject with a 25mm Plossl. Yes, I had tried a 10mm and a 32mm but the 25mm gave me the best results. Peering down the eyepiece, Hazy blotches but distinct spiral structures are emanating from the soft glowing core of M51. Of the two major spiraling limbs, the one stretching all the way to NGC5195 or the one with the southeast orientation, will be the one sporting the newly discovered supernova. Four tiny specks of starlight ranging in magnitude from 13 -15 located on the southwest side of the Whirlpool and lined-up from East to West are clearly visible when using the cone receptors within the corners of your eyeballs. Averted vision here my friends, or you will miss the whole point. No pun intended! From recent photo submissions to various popular social websites, I made a mental note to see the whereabouts or location of SN2011dh. It’ll be nested on the spiral arm which embraces NGC5195 or the one facing the southeast coordinates.Much better seeing than explaining but after plotting their correct places among the broken segments of spiral arcs- one of the specks surely did fell where the photos had indicated it should be! I concluded my quest and my sketching for the night was done. Enjoy!

Dark and clear skies to all,

Juanchin 😀

Supernovae in the Whirlpool

Object Name: 2011dh
Object Type: supernova
Location: Cherry Springs, Pennsylvania
Date: June 5, 2011
Media: digital

Notes

High absolute humidity made the dust lane detail in the western arm invisible, and the dust lanes in the outer arm to the south and east required special positioning of the eye. In this respect, the view was much worse than last time I observed M51 this spring. All details in the arms also looked “fatter.” On the other hand, the view this time was consistent throughout the night, and with the supernova (marked on the sketch) it was well worth staring at.

Earlier last week, when the supernova was already there but not yet broadly announced, and not yet known to me or my fellow observers, some gentlemen on the field suggested that I should look at M51, because it was so nicely positioned. I did not heed their advice, thinking that with the summer humidity, it would be hard to surpass the view I had earlier this year, and absorbed myself with some new objects. I had my earlier sketch with me in my journal (the rough ball-pen original), in which the superimposed stars were marked way below the magnitude of the supernova. It would be fun to make the discovery at least for myself if not for real, but even that apparently was not fated.


Magnitude 13.4 and Rising

Object names: SN2011by, NGC 3972, NGC 3977
Object types: supernova, galaxy, galaxy pair
Location: Cherry Springs Dark Sky Park, Pennsylvania
Date: May 5, 2011
Media: digital

Notes
16” Dobsonian, 75-300x. The supernova SN2011by is the brightest star in the field. It is superimposed on the NE edge of the elongated galaxy NGC 3972, just to the left of the galaxy’s core in the drawing. The round galaxy is NGC 3977, in which recorded supernovae occurred in 1946 and 2006.

As of this writing, supernova 2011by is still the brightest currently in the sky, and still rising at magnitude 12.5. The magnitude in the sketch title refers to the time of my observation. It is in NGC 3972 right next to Gamma Ursae Majoris. This is very nice intermediate-inclination spiral that I saw last year with my 4”. I still retain the mental image of a nicely elongated blob. It can now serve me as something that supernova photographers would call the “pre-discovery image.” SN2011by was discovered at the end of April. At the redshift distance of NGC 3972 (46 Mly) it should become mag. 11.5, according to my rough calculations, and at the mean Tully-Fisher distance from NED (18 Mpc) it should still become 12.0. I.e. it might become a worthy target for “department-store scopes.”

I was curious about the structure in the host galaxy, which is featured in The de Vaucouleurs Atlas as a paradigmatic SA(s)bc. The southwest edge, which is opposite the supernova, is the one closest to us, judging by the photos. I thought that with some appropriate effort expended, the arm running along this edge and even some enhancements in it could potentially be visible in a 16”. But, somewhat disappointingly, all I could see was this edge being sharper than the one with the supernova. The view was essentially identical under a range of magnifications from 100 to 300x. On the other hand, this means that my “post-discovery image” (the view through the 16″) is only subtly different from my “pre-discovery image” (last year’s view throught the 4″), as far as the galaxy itself is concerned.

The field overall is very impressive. Not to mention the supernova, the elongation and asymmetry of NGC 3972 have their counterpoint in the perfect roundness of its apparent companion, NGC 3977. Unlike NGC 3972, this face-on spiral could not be just casually swept up last year with the 4”, and I did not stop to look for it then. NGC 3977 itself was host to two recorded supernovae, 1946A and 2006gs. About them I can only find that 2006gs reached mag 17. The only distance for NGC 3977 in NED is by redshift, 263 Mly. This is far indeed – 5 times farther than NGC 3972, adding to the perceived depth of this remarkable field.

At the eyepiece, I make a schematic in ball pen that records the essential information about positions, sizes, and the contrast, and concentrate on preserving my dark adaptation and building the mental image instead of detailed sketching. Subsequently I use a pressure- and tilt-sensitive digital pen tablet to simulate pencil, blender, and other traditional tools, to create the clean digital drawing, concentrating on conveying the visual appearance of stars and nebulosity.


Taurus in the Year 1054

I send you an illustration of what happened in Taurus in the year 1054 A.D.
This is the supernova which created the “Crab Nebula” (M.1).
Nearby to NE is the cresent moon. On old drawings on stones and so on,
the cresent moon was there when the SN exploded on 4. July this year.
More info on my sketch!
I used pen and pencil on white paper and inverted.

Barlow: GSO three-element 2.5x
Turbulence: 3/5 (regular).
Seeing: 4/5 (good).
Fair wind, no clouds, high temperatures.

If you are allowed to point your telescope (or even a bino) toward south, you’ll be able to see this stunning deep sky object. I was waiting Saturn to rise, the sky was nice, cloudless. I had observed this object sometimes before, without knowing its name. That night I decided to sketch it, so I could search for its name later. Positioning each star was surely the hardest part. I’ve observed it from my backyard, not thoroughly dark, but enough to see incredible features, specially using the barlow lens. The Keyhole Nebula, inside Eta Carina Nebula, was amazing. That’s the way I like to sketch: knowing nothing about the object in advance, not to influence the register. I prefer researching about it after observing, it’s much more pleasant. I hope you enjoy it, I loved the image I’ve seen.

Clear sky to all,

The hypergiant star VY Canis Majoris is not a particularly well known observing target, but it is however a very interesting object.

Sometimes referred to as the “Little Humunculus” this object is currently thought to be the largest star in the Milky Way.
Visually in the 56cm dob at fairly high magnification this strange object exhibits a tiny tail of ejecta as can be seen in the sketch.

The last time I observed this star was about 4 years ago in my old 41cm dob when I looked at it a couple of times over a three month period and
noticed it to be slightly fainter on occasions, so it must be slightly variable.

The first mention of VY Canis Majoris was in a star catalogue by Jérôme Lalande in 1801, where it was listed as a mag 7 star.

Needless to say that it is a star of stupendous dimensions estimated to be around 1800-2100 solar radii, and about 450 000 times brighter than our sun.
However the true size and nature of this remarkable star is still debated.

It is a highly unstable star that is shedding an immense amount of mass and is quite possibly a supernova candidate.

After an enjoyable night of observing faint and somewhat difficult to find galaxy clusters I settled on NGC 4088 with its new supernova as my final object. Well, it seems I saved the best for last! 4088, also known as Arp 18, is a terrific spiral galaxy with obvious asymmetry to its spiral arms and a bright supernova near its core. This was a visual treat as well as an opportunity to ponder the reality of a star blowing itself to to bits.

The sky had variable high clouds all night but at the time of this observation was at its clearest. Three nights later under a clearer and darker sky, with an SQM reading of 21.51, the view was much the same but the supernova had noticeably faded. Even so, NGC 4088 has become a new favorite and I’m grateful that SN 2009dd brought it to my attention. Perhaps the most startling fact of these observations near the April new moon were the run of clear nights that made them possible – a rarity indeed in the Pacific Northwest.

Starting with a scan of my eyepiece pencil sketch, I used the blurring and smudging tools in Adobe Photoshop Elements to smooth the rough areas into a more natural look. I made the stars round by using the eraser and pencil tools, and then touched up each star with a couple of clicks of blurring. I finished the image by inverting and adjusting the brightness and contrast levels.
