This set contains a couple of correction to the archive claims. First, SOHO-4256 had already been confirmed as SOHO-3488 -- many thanks to Simone Renai for pointing that out to me. Luckily, Peter made a couple of more non-group reports, one of which fit perfectly into the vacant position, and the other becoming SOHO-4263, so I have added these to the list. I believe these discoveries take Peter past 50 comets - many congratulations, Peter!

Second correction is that SOHO-4251 was more likely a Marsden-group than a Meyer group comet.

As discussed on the page, the Kreutz stream has made its way back in to the STEREO/HI-1 field of view again. Right now only the brightest Kreutz will show up in HI1, but by mid-to-late September I would expect HI-1 to see almost every Kreutz that we discover in SOHO. Once we get into mid-November, we will go back to only seeing the brighter Kreutz, and then probably by mid-December the Kreutz trail will leave the field of view again until summer 2021.

Best wishes, Karl

EDIT: SOHO-4272 was a joint-discovery between Worachate and Peiyuan.
