archival Kreutz comet


Hello all!
Yesterday I reported a Kreutz on archival images from 2021-04-19. I checked a list of comets and legacy reports, but I'don't see a comet with this date, and with those coordinates. I have no confirmations for report. 
Please, could anyone check this one and give me own opinion about it?
Thank you in advance.
Best regards
Rafał Biros
