Spectacular view of the supernova in M82 on the night of January 25, 2014
Scketch made at La Hita´s Observatory in La Puebla de Almoradiel, Toledo (Spain).
22:18 UT
With graphite on white paper, looking through TEDI telescope (770 mm, f3.2 ) eyepiece 13mm and the red light of my torch (I call it “the demon” by its two red eyes).
The sky was really clear and pristine, relative humidity 80%. (4.5ºC)
Close to new Moon. My estimate Mag with reference stars is 10.5

Hi All, here is my sketch of M82 with the glorious Supernova, such a privilege to be able to see such amazing happenings in the universe from ones own garden 🙂
My estimate of current magnitude is Mag 11 to 11.5 using local stars as known reference.
I hope that you get to see it soon too, if you haven’t seen it already.
Good Night, Dale

Hey ASOD!
I send a sketch of the great supernova in the galaxy M.82.
I could not detect any color in this SN, it looked white to me!
I also observed the SN in M.81 in 1993 (ASOD-gallery).
My sketch here is made with colorcrayons on black paper.
Location: Trondheim, Norway. Info on my sketch.
Best wishes from Per-Jonny Bremseth.
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.
• Object Name: M 74 and NS 2013ej
• Object Type: Face-on spiral galaxy with a supernova
• Location: Bonilla-Cuenca Spain
• Date: August, 11th, 2013
• Media: Graphite Pencil HB 2, torchon 1 and 130g drawing sheet
• inverted colors with GIMP 2.8
Observation notes:
The supernova is shown as a little star in the middle of the southern disk of the galaxy. Of the five stars, I meet in front of M 74, the supernova is closest to its center.
Its brightness is very similar to the nearest star to the west and also to the middle star of the three that are on the eastern edge of the disc (picture below).
Greetings to all visitors of this page.

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!

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!

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 😀

Hi all, Supernova SN2011DH was easy to observing.
And I saw beautiful arms and bridge.. Because seeing is very good!
