Hello again.
This is my latest sketch. I drew it form the town center where there is a quite big light pollution.
At that time I didn’t see the comet tail. The most amazing thing was how fast it was moving across the night sky.
Object Name:
* Object Type (Comet)
* Location (Skawina City in Poland)
* Date (01 February 2009)
* Equipment: Synta 8” Dob, Eyepice SP25 mm.
Greetings,

Comet C/2007 N3 Lulin
Sketch and Details by Frank McCabe
C/2007 N3 (Lulin)
I got my first “good look” tonight of our bright visitor after moonset and none too soon as the comet and earth distance begin to increase. I made a quick graphite sketch under the starry canopy. I was out observing the moon from twilight until moonset. That allowed the comet time to reach nearly 58 degrees in altitude before I turned my attention to Lulin.
Here is my (inverted graphite) sketch
C/2007 N3 (Lulin)
March 1, 2009 4:30-5:00 UT
Magnitude: aprox. 6.2
Transparency: 4/5
Seeing: 8/10

Comet C/2007 N3 (Lulin) and Saturn
Sketch and Details by Leonor Ana Hernández
COMET LULIN c/2007N3
The medium used: graphite pencil.
Negative image.
The equipment used: 12×80 Binoculars (Field 4,2º)
Date: 23-02-2009
Place: Cuerva (Toledo, Spain)
The night was explendid, clear and cold (1º C).
The Sky Quality Meter (SQM-L) shows 21,17 mag/seg arc^2
The comet and Saturn was in the same field of view, separated 2º aproximately. At 23:30 TU the coma was located between the stars HIP55574 and HIP55467 of Leo. The coma´s diameter fills the space between them completelly.
The tail was wide close to the coma but very thin at the end.
Quite visible and noticeable. The tail points to 80 Leonis and exceeds it with averted vision.
The nucleous was intense but not a like-star.
Saturn was fantastic with a pale yellow light and the thin ring that crosses the planet, like a cutter line. And Titan very close…
Unforgetable night!
Leonor

C/2007 N3 Lulin on February 25th, 2009
Sketch and Details by Jeff Young
After striking out for nearly a week running, a comment on one of the Irish boards got me to thinking. The gentleman was describing driving home and pulling over to get the binos out when a partial clearing presented itself. It finally dawned on me that I needed a more opportunistic approach to deal with my constant cloud cover. Checking two or three times a night to see if it was clear out wasn’t doing the job.
So I duly set up my p-mount & binos in a south-facing window, pulled up a chair, set my sketching stuff on the window cill, and sat down to wait.
Over the next hour and a half I was rewarded with 3 spells of pretty good clarity and 4 or 5 spells viewing through high thin clouds. Lulin was easy naked eye during the clarity (although it appeared stellar — no coma visible), and I’d estimate its brightness at better than mag 5.
I was able to work on some of the brighter field stars even through the high clouds, although I never got enough clear spells to plot all the dimmer ones (I worked mostly on the comet itself during them). The time listed on the sketch is when I plotted the comet’s position relative to the field stars. I was working on the sketch from about 23:20 to 0:10.

Solar Prominences in H-alpha Eastern Limb

Solar prominences in h-alpha, eastern limb

Sketch created scopeside with black Strathmore Artagain paper, white Conte’ crayon and pencil, white Prang watercolor pencil.
Temp: -5.2° C, Humidity 74%
Seeing: Wilson 4, Transparency: very poor with improvement
Cirrus to the south, winds 5mph SE
Alt: 33.6, Az: 143.9
The eastern hemisphere, especially east to the northeast, was scattered with prominences. As transparency improved, details of these little prominences came to light. The most obvious set was around 90° position angle and then a squat hedgerow one around 40°. I stopped my first sketch midway and began a fresh one with a larger limb span to include the majority of them, most which were faint and whispy or very tiny.
I counted 8 more small slender ones that weren’t included in this sketch. I’m sure that given a little more time (or perhaps ambition to stay out there longer) the improvement in transparency would have revealed a few more. There was a very sharp small plage about 20 degrees in from the north limb as well as a few very hair-like filaments, particularly west, south, and east. It is reported by another solar observer that there are two new spots in that same location, indicating a new AR.
M108 (NGC 3556) Galaxy in Ursa Major

M108 (NGC 3556) in Ursa Major
Sketch and text by Kiminori Ikebe translated by Eiji Kato
This is a galaxy near M97, the Owl Nebula. It is quite bright and large with a mottled surface brightness hinting at some structures. It is has a narrow elongated shape, but unlike edge-on galaxies, it does not have a central condensation or sharply defined outline. It seems to be split into three regions. There is a small isolated area at the western end of the galaxy. The center of the galaxy is elongated and the eastern part is faint and diffuse. There is a star on the western side.
Date of observation: 2001/11/24 05:22
Observing site: Kujyu Mountains, Japan
Transparency/seeing/sky darkness: 3/3/4 of 5
Instruments: 50cm Dobsonian with XL14 at 160x

Comet C/2007 N3 (Lulin) and Saturn Conjunction
Sketch and Details by Jef De Wit
First my big appreciation for the website. I was a fan of APOD for years and discoverd ASOD only two month ago. Even the members of my astroclub specialised in sketching didn’t know of the website! I try to motivate them to send some of their best pictures, but I think I have to give the example first. I hope you like mine sketch.
The weather in Belgium was (and is still) very bad. I tried to see Lulin for several nights without any result. The 24th this month there was a brief opening around 3.30 (local time) in the clouds for about 20 minutes. I was on holiday and had only my binocular (7x50mm) with me. The observation was made from a balcony on the 10th floor. I had to lean – not without any danger – over the realing to see the comet, so I couldn’t install my tripod. To bad, because the binocular handheld there were no details vissible. The comet was a round, uniform spot in the sky. But that doesn’t matter, the conjunction with Saturn was a beautiful sight. I made a sketch and went outside in the hope to install the tripod. But the time I arrived downstairs the clouds were again omnipresent.

The night was very freezly,the light icely wind passed over my face,but the sky was dark and clear,normal situation in winter.I take my big bino on wood’s tripod and made that sketch.Beautyfull vision, the comet was very bright, with tail and anti tail visible with difficulty.
I sent you the information about this.
