Uncatalogued supernovae that will require reporting

Interesting things Supernovae
1

So far between 2022 and 2025 I have discovered around a dozen uncatalogued supernova candidates, but have not yet been reported in the Transient Name Server.

The following six supernovae were discovered from September 2022 through July 2023, upon investigation were not found in the TNS and RBS pages, nor in NED or SIMBAD. Their existence has been verified through the examination of single exposures visible in at least two nights.

Recently, I have joined the search again for more supernova candidates, specifically ones discovered going through historical astronomical catalogues.

Remarks: The supernovae discovered in September 2022 were only visible in DR10 early, but are no longer visible in any images from the DESI Legacy Survey. The object found on March 11th 2023 has data from onbly one date. A minimum of two dates around close proximity should be allowed. The supernova found on March 28th 2023 was previously reported, but the magnitude and bands were incorrectly reported,

I wanted to bring up this note regarding the supernova candidate found on March 28, 2023 (fifth in consist) This is a candidate SN that was reported by my son as AT 2013ht and it has incorrect information on it. On the TNS page there are two comments on the bottom that discusses the corrections to the band and magnitude. So far this information has not been corrected but I would like to send an email to the folks at the TNS to change this. For some background please see:

I don’t have a TNS account to report SNe and AT’s but my son does. We are still deciding whether to report them soon, moire than likely after 2013ht thing gets resolved.

ALSO: From what we can understand what happened is that there was some confusion between the measurements of magnitude and flux when reporting and that it was his first time ever reporting an AT. The text reads “Mag. / Flux” and took the measurement of flux in g-band. Also since the transient was detected in two bands, the r-band was incorrectly assigned instead of g-band as intended.
