Lulin Brightening for Sketchers- Congrats Jeremy!
Posted 28 January 2009 - 05:00 AM
but could not find it here in the sketching or imaging forum.
I also wanted to alert others that this is becoming a good target for DSO sketchers. It is currently at naked eye threshold mag 6. Reports of it seen as very green and will brighten into February as it now shows a significant tail and anti-tail. (Yet I have not had a chance to get up early and have clear skies for it yet.)
I could not find too many posts here in sketching aside from Special Ed's nice sketch posted on Dec 30th >
or only one in photo imaging or general observing aside from seeing Jeremy's in Spaceweather.com.

Mark- Thanks for pointing it out.

I would love to take a look at Lulin but one must have clear skies to see. It looks by the weekend the skies will clear for three or four days . . . I hope.
Thanks Mark for pointing this out.

Very nice, look forward to seeing your most recent sketch of the comet.
Mark, thanks for pointing us to this sketch.

Great sketch and report. The comet does look impressive in your sketch above and larger and brighter than in your earlier sketch and report.
Clouds continue to block my morning sky but eventually a break will let me get a first look.

The comet is truly amazing from a dark site. Both tails materialized readily in the binocular view. The dust tail was bright and distinct, while the the ion tail, although immediately apparent, still took effort to inspect in detail. My sketch can't come close to describing how beautiful it was. It was like a foggy sunrise over a softly glowing horizon with a subdued but lustrous sun glowing in the middle. The telescopic view presented a huge coma, nearly a degree in diameter and a stellar pseudo-nucleus. (Higher power--240X--showed the pseudo-nucleus to be a circular dot perhaps about 4 arc seconds in diameter.)
The full report and large/labeled sketches can be found here:
C/2007 N3 (Lulin)
Attached below is the naked eye sketch, prepared with graphite on Strathmore 80# Drawing Medium 6" x 8". Nothing special. I used the blending stump to shade a bit of glare around Porrima.

Thanks for posting this fine set of sketches here. I like the evolution from naked eye to binocular view to telescope. I had the first two views on Feb. 21st and your drawings reflect what I saw from my dark skies very well. [Since I'm recovering from a bad case of the flu, my wife wouldn't allow me to set up a telescope in the 15Â°F temp we had--I didn't really have the stamina anyway--so I bundled up in hat and coat and enjoyed 15 minutes looking through an open attic window.]
The binocular and telescope sketches are blended beautifully and realistically portray the subtle variations of the coma and tail--very masterful. Excellent observations.

very fine sketches! In Germany we have rainy weather, I am waiting for clear sky to sketch Lulin.

Excellent observations and reports on this interesting comet. My observations of the comet agree with your own. The ion and anti-tail are interesting but, as you point out, will be in the same direction after opposition. I hope to be able to follow it soon.

Your most recent sketches of comet Lulin are up to your established level of excellent. Beautiful! I enjoyed your well written report and your photos at your web page.
I am hoping for a few clear nights this week.

Michael, sorry to hear about the flu...as if dodging persistent, cloudy weather weren't enough. I'm glad you managed a 15 minute attic session!
Something interesting I learned earlier today, 9th magnitude asteroid 29 Amphitrite was being overrun by the comet while I was making those observations. It can be seen right next to the pseudonucleus in both the binocular and telescopic sketches. I think that's one of the great benefits of sketching: that I can hear the news, backtrack to planetarium software, check positions & then pinpoint it on the sketch enriches the experience even more.
I'm really hoping some of us get a CSC that shows a blue window Wednesday night for opposition!
