Here are confirmations for archive reports, and one correction.

So originally I had confirmed all the archive comets (through SOHO-4464) and was about to start June confirmations. But then I saw Hanjie posted a set of archive claims so I decided to include those as well. Normally I try and keep archive reports in order of 'image date', but I made an exception here.
Note that I verified that SOHO-4447 was NOT the same as SOHO-2827. I also verified that SOHO-4457 was not the same as SOHO-4043 (which was just a couple of hours ahead of this one).
I could not confirm Hanjie's report from report_ht_20220527002054 - the positions did not align well at all, and I tried several times to get better observations.
SOHO-4462 is interesting. Qicheng Zhang (astronomy PhD student) emailed me to point out a very faint fragment leading 323P/SOHO in data from January last year. It's very small and faint but definitely real. Comet 323P/SOHO has been in the news recently thanks to a newly published study from Man-To Hui that used a number of ground based observations of the comet to show that it is very much in the process of being destroyed by its repeated exposure to the near-Sun environment. So the discovery of this fragment is certainly not a surprise, and fits nicely into the narrative of repeated fragmentation/disruption. Congrats on your first discovery, Qicheng!
Via Rainer Kracht, SOHO-4464 is almost certainly a return of C/2004 B3 = 2009 V10 = SOHO-3081, although the timing for C/2004 B3 seems a little off (but only by about two weeks). Sometimes I do not assign SOHO numbers to 'known' returns of SOHO comets, but I typically prefer to wait for them to receive P/xxxx designations first. So I have numbered this one.
I have designated SOHO4471 as a Marsden-group comet, although Hanjie labeled it as non-group. To me, it follows the February Marsden track quite well, although did look somewhat diffuse, which is very unusual for those objects. So we will see what the orbit ends up looking like when it gets calculated. (Speaking of which, I hope to have good news about that in the coming weeks...)
That leaves us up-to-date on archive reports, and I will probably wait until next week to post the June confirmations. As always, email me with questions, comments, etc.
