Announcement: New Applications
We are excited to announce the launch of our new applications! We're opening up early access to our new applications for searching, downloading, and submitting photometric observations. You can now access these applications through these links:
We ask for your feedback in order to help us improve these applications. Please send feedback for the applications above to feedback@aavso.org. Note: please avoid duplicating submissions across the two submit applications.

does the sudden drop of magnitude in the light curve after about 80 days an indication of a black hole? Or, am I misinterpreting the possibilities? I can find no conformation on the web...Lane
Though . . . calculating the gravitational effects of the collapse would be fascinating. The size of that supernova appeared to be enormous. I missed photographing it by 36 hours. I happened to be photographing M101 from May 16, 2023 through May 18, 2023 before the clouds rolled in for a couple of days. (It's generally been a miserable year for astrophotography and photometry at my location.) To think about the swath of space that supernova impacted is mind-boggling.
never mind, I found the answer - it is caused by the ionization/re-ionization of Hydrogen...Lane
