hm ph: 520-586-2244 Far better, I thought, was the MPEG sequence you can make
yourself from the latest LASCO C3 images. I usually choose the last 100 images,
but you can choose a range of dates, too. See if this site works:
http://sohowww.nascom.nasa.gov/data/LATEST/current_c3.mpg To say it's
spectacular is an understatement. It reminds me of the HST sequence of images
of the middle of the Milky Way as stars loop around the central black hole.
Very compelling evidence for its existence. Has anyone tried to see the comet
visually yet? I tried, but no luck. Is it going to be a morning object?
Clear skies,
Wayne (aka Mr. Galaxy)

An interesting sungrazing comet will be entering the field of the SOHO LASCO C3
camera on Wednesday.� At that time, it's expected to be around magnitude
5, which should make it easy to see in the frame.� Then it may reach
magnitude -2 or so before it almost certainly gets torn to shreds by the
sun.� If it somehow survives perihelion -- which is only one-tenth of
the sun's diameter -- it may become visible in the night sky.
The comet was discovered by Terry Lovejoy in Australia, who uses an inexpensive
setup with a C8 and a consumer-level camera.� It is extremely rare for
sungrazers to be discovered in this manner.� Terry has discovered more
than 140 sungrazing comets by looking at frames downloaded from orbiting solar
observatories.
A good source of information for this comet, presented blog style, is the
Sungrazing Comets Web site (they've got a site for everything!) run by Karl
Battams.� http://sungrazer.nrl.navy.mil/index.php?p=news/birthday_comet
.� Already the comet has entered the STEREO (Solar TErrestrial RElations
Observatory) frame, as you can see on his site.
Comet Lovejoy will enter the SOHO LASCO C3 frame from the south early on
Wednesday.� Look for it at this site.

It's possible that we will get to see the destruction of a sungrazing comet
this week.
