Comet Lulin still looking good

This unexpected bright comet has been a pleasure. I've posted some of my photos of this comet on my blog. But there are some other nice photos by others too.

Iceball falls into the Sun

On Feb. 23rd, 2009, the Solar and Heliospheric Observatory (SOHO) observed a comet plunge into the sun and disintegrate. This one was part of a family of small comets called Kreutz sungrazers which resulted from the breakup of a giant comet s over 2000 years ago. Most are small and faint, but this one was a beauty. Watch the movie of its demise. The comet appears coming up from the left at around 8 oclock. (The black disc is a coronography type instruments that shield the Sun to show the surrounding area).

Green Comet, blue stars and now a comet tail

Last night February 28, at Powell Observatory, 20 minutes south of Kansas City, we welcomed w about 200 people who wanted to observe the comet through our 30 inch telescope. The snow had stopped, the clouds disappeared and we had color clear weather. The green comet was glowing at 6th magnitude. It now was up and south of the bright star Regulus. People could see its coma (cloud like area around the comet head called the nucleus , which you can't see in this photo) and nucleus which was near the center but was more difficult to observe. (Photo taken by Eric Flescher through 6 inch telescope,60 seconds- I am workin on the color photo).
Another person in Italy took a picture of the green comet when it was near bluish Spica a few days ago (we had clouds during this close approach). You can see it at

On 2/25/2009, I took more photos of the comet. The tail is now easily seen and more pronounced as it has swung around Earth and now away from it, heading toward the outer reaches of the solar system. The tail is out to the side instead of behind the coma so we can now see it. Now the view is more like what we normally think of a comet, with it's nucleus having a streaming tail (boiling off by the Sun's energy), pointing away from the Sun.

Mardi Gras' Fat Tuesday’s Green Smudge Comet Lulin nearest 2/24


It was my hope to take photograph the Mardi Gras Fat Tuesday’s Green Smudge Comet Lulin. I wanted to show what Comet Lulin might look like with out a big telescopic view, from a city or slightly darker area to simulate what most would see as the comet comes closest to Earth on 2/24. I tried a couple of weeks ago but no success.

Last night 2/21, I tried again at Powell Observatory, Louisburg, KS just south of Kansas City. Some people said that the comet could now be spotted with binoculars and even naked eye! And I saw it had brightened and could see both these views as well as in our 30 inch telescope.

0n 2/21/09 returning back to Powell, I saw the brightening comet. The nucleus was brighter and so was the rest of the comet coma. It is moving away fast from the Sun.
We could see it moving across the the telescope's field. The coma was bigger and one side (left) was brighter. We could see it easily with our binoculars and could see it (naked eye) as a smudge below Saturn.

This time I was successful using my Canon Rebel XT with 55mm lens, ASA 800 at 30 seconds f/6.3.
You can see the smudge comet (6 magnitude) in the photo just under ) the 3.56 star Zanijava which is just below the brighter planet Saturn (mag 0.56) to the left of the bright blue star called Denabola, in the constellation Leo . Since it was 11:00 CT, the comet was still coming up from the East horizon and still drank in some of the lights from the horizon. Still I was glad to image it . If I could see it with naked eye and binoculars and image it without a big lens (my next attempt), you can too!

Additional information

Comet Lulin, discovered at an observatory in China , is now brightening for a date to be nearest Earth on Feb 24. Now at mag 6 we hope it will brighten to 5th. I saw it with our 30 inch telescope a couple of weeks ago using our Powell Observatory’s 39 inch telescope. Its greenish colored and was difficult to see. The nucleus was even more difficult to see.

This photo on APOD is like what I saw of it and sketched from last week. A tenuous circle like cloud like coma with viewable but difficult to see nucleus right in the center.

if not 2/21 look at archivescan't find it? use the archives and go to earlier date other then this one

Also there are several nice photos on spaceweather.com

Also nice article and more pics at

Comet Lulin is approaching

The greenish looking Comet Lulin, has a tail and will reach maximum magnitude in February. While I have not seen it yet, others have and photographed it.
Here is one of the latest links to one . (if you have your own on a website please send me a link or send me your photo or sketch and I will publish it on the blog with your permission and citation)

Comet 8P/Tuttle




Comet 8P/Tuttle is heading toward Earth. On Jan. 1st and 2nd it makes its closest approach to our planet--only 24 million miles away. The emerald-colored comet will brighten to a predicted magnitude of 5.8, visible to the unaided eye from dark-sky sites and a fine target for telescopes.

Latest pics in spaceweather.com archives
Map here too

My canon is in the shop but I will try CCD imaging at observatory I use and Harvard scope if it clears
Meanwhile I was going through my images to discover which comets I did not pick up. Here is comet Faye 2/27/2007
