The last few of these are out of sequence because I forgot about the chat group reports, and it is too much work to renumber the comets to put them in sequence :)
I still have a LOT of archive comets to look at, including a couple that Wenjie and Jiangao have asked to me check again. I will get to those in time, but I am behind on the realtime comets, so they have take some priority for now.
One other thing I wanted to tell you all about. I was at a comet meeting in Arizona a couple of weeks ago, and got to spend some very productive time talking with people from the MPC about getting the SOHO comet data published. We have been talking by email for some time now, but face-to-face interaction is always more productive. Anyway, I think we have reached a good agreement on how to go about getting the SOHO backlog actually published via the MPC, and get all the comets officially designated. So in the coming weeks you might start to see random SOHO comets being published. Initially they will be out of sequence, as we provide different test cases to them on a limited basis such that they can learn how to handle sungrazing comet orbits. But eventually this should turn into large-scale production of designations. I'll keep everyone posted.
Oh, and one other great thing about that meeting is that I got to meet Hanjie Tan! He is an astronomy PhD student current based in Prague, and was there presenting his research. It's always wonderful to meet any of you in person, and it's truly fantastic that so many of the young project participants go on to pursue astronomy or space science-based degrees in college! Indeed, not only was Hanjie at this meeting, but so was Quanzhi Ye and Man-To Hui -- both of whom were teenagers discovering SOHO comets and are now my colleagues/collaborators! The Sungrazer project is uniquely successful in the rate at which young participants end up pursuing STEM careers, and I hope that always continues to be the case. I always strongly encourage you to introduce young students to the project, mentor them in how it works, and hopefully see them flourish!
As always, email with questions, comments, corrections, etc.
