Solar Serpent

Solar Filament & Prominence - 26 April 2015
Solar Filament & Prominence – 26 April 2015

Aloha!

I was delighted this morning to find this dark and large filament at the north-eastern limb of our Sun. It had the appearance of a large serpent with foot like projections anchoring it to the solar surface and then visible curving around the limb. The filament is magnetic curtains of plasma hovering over the Sun’s surface, this an especially large and detailed one. I read on the Spaceweather site that the length of the filament would measure the distance from the Earth to the Moon. That’s one big serpent!

Posidonius Crater

Posidonius Crater
Posidonius Crater

Hi all,

yesterday evening just before the altocumulus clouds of the approaching depression covered the sky, I could do another sketch of the moon: This time it was crater Posidonius and its surroundings.

Ah, by the way, this time I tried a new pen: For the bright areas (e. g. the western rims of Posidonius A and J), I took a whitecoal pen instead of chalk pen. That provided much brighter contrast.

Another novelty for me: I didn’t use a diagonal but an Amici prism, so that the view in the eyepiece wasn’t mirrored at all. The view was a bit less bright, but for the moon it’s still bright enough.

Craters Diophantus and Delisle

Craters Diophantus and Delisle – Labeled

On the western side of Mare Imbrium are craters Diophantus (19 km.) and Delisle (25 km.) with mons Delisle in between and closer to the crater of the same name. A dorsum or ridge here is perhaps a buried crater rim and creates a sharp edge curving demarcation on the terminator side of the Moon at the time of sketching. Some of the massifs in this region such as mons La Hire (1.5 km. high), mons Vinogradov (1.4 km.) and mons Delisle( 0.8km. high) are described by some geologists as likely left over remnants from the rings of the Imbrium impact. Additional craters seen at this observation included Euler (2.8 km.), Artsimovich (9 km.), Gruithuisen (17 km.) and Heis (15 km.)and numerous smaller unnamed.

Sketching:

For this sketch I used: black Strathmore 400 Artagain paper, 9”x 12”, white and black Conte’pastel pencils, a soft charcoal pencil, brush and a blending stump.

Aloha!

I think what I like best about solar observing is you never know what you will find going on! This large prominence at the eastern limb appeared extraordinary in its detailed and lacey appearance. Seeing was very good and at higher magnification a network of bright areas appeared, much like a picture of a neuron cell with branching filaments extending in all directions. Tilting Sun Graphics are used to denote prominence location.

Webmaster’s note: ASOD is experiencing problems with sketch submissions where the file size exceeds the limit of the ASOD WordPress programs capability to process the file. Please be aware that when this occurs, although we do have some graphic editing programs, large files will result in two or three iterations of resizing, that may still result in a sketch that cannot be downloaded to the ASOD template. Due to the fact that I have a day job, I often put these pages together late at night, and being very tired I have difficulty trying to bring these posts together. Please be aware that we would prefer receiving files that are no bigger than 800 pixels wide. We will always resize your sketch image to 650 pixels to fit on all the the standard protocols for tablets and smart phones. Please make sure the image file size (the number of bytes the image file) contains does not exceed 500 Kilobytes. This will guarantee that your sketch is published in it’s entirety, and on time. If there are any questions, please feel free to contact us here at ASOD, we will be happy to help with any problems that are troubling you with image size issues.

Keep up the great work,

Aloha!

This was one of those nights things just fall together. Excellent seeing and light enough from the Moon that I could see the paper well. After finishing my sketch at the eyepiece I went inside to clean it up and was pleasantly surprised that I liked it pretty much the way it was.

110km wide Gassendi Crater showed some excellent roughened floor details with hummocks casting shadows as well as floor rilles illuminated as bright & dark lines. Rima Mersenius is brilliantly lit on the terminator and the bright scarp of Rupes Liebig can be seen at the base of the wall.

Aloha!

A somewhat cloudy night but the Moon beckoned so I set up my ES102ED. Whoa, whats that? Its Elvis rocking out on the lunar terminator! What a fun surprise to find the dark outline of a figure standing wide appearing to play a guitar! A friend had told me about this phenomenon as well as some of the lunar alphabet visible at certain times on the terminator. I have tried to observe this before but was either too late or too cloudy. This time it was by complete surprise that I found it. I sketched at the eyepiece and cleaned up the sketch later in better light. I was also able to capture “The King” with my iPhone.
The interesting thing is that Elvis (aka Lunar V) is only visible for a short 1-2 hour window of time every month. This perfect angle of light shows not only Lunar V but also Lunar X a few hours after the first quarter. Lunar V is visible at the terminator between Mare Vaporum and Sinus Medii near Crater Ukert. Other landmarks are Hyginus Rille and Crater Triesnecker.

Glenn Chaple wrote about “Elvis and the Alphabet” in the August 2013 issue of Astronomy Magazine. Very interesting to find these “little jewels hiding in plain site” as one reader wrote.
