I'm a chinese and a new SOHO comet searcher , so I'm not very experienced Last week ,Expert Kail confirmed five SOHO comets (SOHO 868---SOHO 872),I'm very...
Hi Xing, ... this really seems to have slipped Karl's attention - no wonder when one looks at the board with such a lot of retractions and false reports....
Karl, I would like to apologize for not sending a retraction on my 2 previous comets. The first was a potential that Tony and I had little confidence in, but...
It's not a problem Gregg, but thank you anyway! Regarding Bo Zhou's claim, I apologise for skipping it! I'll check it on monday but I'm sure it's real. I'll...
Hi group. I have a question that I need help on. If I discover a comet in C3 images and someone else discovers a comet in C2 images around the same time, how...
... If you were to superimpose the C2 field on the C3 field, C2 would extend about 40 pixels below the bottom of the blue occulting disk (likewise, the top and...
You can also "shrink" c2 until the white circle (the size of the Sun) in the C2 occulting disk is the same size as the one in the c3 occulter. ~~Karl...
Hi all, Mercury is now visible in C3. You can find it at positions where Bo Zhou did report a non-group comet... ;) Better to check the C3 transits page. ;) ...
Hi all, Just pointing out the Milky Way now entering the lower-left of the C3 fov -- it's a beautiful sight! While I'm here... there's an alternative source of...
Hi All, See the text of this recent MPEC. Very interesting comments by Brian Marsden regarding possible short-period status on the Marsden and Kracht group of...
I have a couple of questions to ask. Can a Kreutz group comet or any of the others be observed with a telescope right before sunrise or sunset, or does the...
Steve, SOHO Kreutz group members usually do not survive perihelion -- moreover thez do even disintegrate prior to perihelion passage. Therefore it is not ...
Hi Rob, ... yes, indeed. This was already suspected by several people due to the connection to 96P/Machholz, the Quadrantids and the Daylight Arietids. cf....
Hi all, can someone of the archive experts check for a possible associated comet to C/1999 J6 in the 1999 data? It should precede C/1999 J6. But maybe the...
Hi all, To help anyone looking for a companion, see my web page on the comet, one of mine :) at http://www.ph.u-net.com/comets/non-sungrazers.htm#109 Click on...
I loaded in the images this morning and had a close look but could see nothing. Perhaps SOHO's position relative to the orbit of the comet prevented it from...
Hi all, the nice bright comet in SOHO/C3 images was actually found by M. Mattiazzo in SWAN images at the end of November. Provisional orbital elements by...
Nice comet! There appears to be an interesting "sweep" of the tail as it enters C3. I'm not sure if that's real or not. I've made a running difference mpg of...
Hi Karl, ... I noticed the same thing -- it's as if the comet is corkscrewing. I suppose one interesting possibility would be if the comet nucleus was spinning...
Hi Maik, ... I never saw it reported in the MPECs (?). I wonder where it was in SWAN in late November? I kept close tabs on SWAN all through October,...
Hi Rob, ... sure it was not reported, since there were only four datapoints. So we had to wait for it to arrive in C3. ... I will send you a private e-mail...
Here's my take on this: SECCHI is theoretically more sensitive than LASCO -- I believe the COR1 & 2 CCDs are 2048x2048 arrays (which will then be binned down...
Hi list, another fine non-group comet by Heiner! It has brightened nicely while it makes it long swing around the sun. It is also slightly elongated with a...
Hi: How necessary is it to post "Further to my post of..." on a comet find. The SOHO page is overcroweded with this and I think in reality 4 XY's are enought...
Hi Mike and all, The "Further to my post of..." is a very useful option, and one that I'm not going to get rid of. Some of the kreutz comets you guys pick out...
Hi all: I checked the LASCO images and found a potential object , but it's very faint . I couldn't sure it , please help me (yes or no ,why ) . thanks a lot ! ...
Dear Xing, ... I was not able to check the object itself - since I do not have tried to find a convenient way to get rid of the darkness in the edges (I mainly...
