G'Day All The recent solar storms may make comet hunting a little harder, via @SunGrazerComets https://twitter.com/#!/SungrazerComets/status/177733885864574977...
G'Day All Comet SWAN is in LASCO C2 and STEREO Behind COR2 and COR1 beacon images. It is evaporating. http://stereo-ssc.nascom.nasa.gov/cgi-bin/images Cheers!...
This comet found in SOHO C3 did not show to much of a tail, but definitely had a longer tail as seen in COR2 images rgds Alan. STEREO COR2B (0,0)uplft Label X...
Gidday all, I have been playing with Helioviewer and SDO images, found the image download button. Thought to share some images here, Lovejoy looks interesting....
NOVA SAGITTARII 2012 = PNV J17452791-2305213, becomes apparent in STEREO HI1B imager across 20120420-23. should be there for a while and we may see the fade...

Here's the same data converted into an estimate of stellar magnitude http://stereo.gsfc.nasa.gov/~thompson/nova_sagitarii_2012_mag.gif Bill Thompson ... -- ...
Alan: Good catch. I thought you might be interested in this crude light curve that I derived from the HI images. The units are arbitrary--I haven't tried yet...
G'Day Alan Great catch, looks terrific. My only question is how you did the processing. I did a standard stack, min z project subtraction and I get a fair bit...
Gidday Ian, The more frames you can get in the sequence the better the min z projection frame will be. Make a stack of up to ten days, say 20120420-26. Remove(...
A couple of possibilites, Bo Zhou recent non group, or early Phaethon or return of expected soho retrun metioned by Rainer a few months ago? still checking....
Gidday All, Suspect it is *(3200) Phaethon* return, if others could confirm, would be appreciated. Any measurements of magnitude will be affected by CME...
Looks a little fuzzy to me, but other again can confirm. Likely to fade out as it moves up. Tomorrows images may answer the big question about Phaethon?...
Gidday Alan, yes it looks like 3200 Phaeton. I have measured the 20120430 images and the orbital elements derived from those measurements are quite close to...
Thanks Rainer, just about to check today's images, looking for any interactive tail activity. 8) kind regards, Alan. ... -- Kind regards, Alan Watson...
A small avi of Phaethon at my blog for consideration. http://cometal-comets.blogspot.com.au/2012/05/phaethon-returns.html I processed it from raw FITS by doing...
Hi William, U've done an excellent job! I venture to bet that you're using IDL for data mining judging from the style of the graph. I'm willing to know more...
Gidday All, The STEREO Satellites have been in solar orbit for about 5 years now and have seen the complete Ecliptic star fields five times also. I have been...
Thanks Ian, I am half way through sorting the STEREO HI1A data for 2008 -2012, about 800GB, takes 6hrs per year using a PC, into a directory structure that ...
