SN 2021ucg - Type II Supernova in UGC 12188
Posted: Fri Oct 08, 2021 10:44 pm
Going for the "smaller" objects again and decided yesterday to go for the interacting galaxy pair UGC 12188, apparent size 0.56 x 0.347 arcmin.
And today I checked the data collected so far in Aladin with the Simbad and NED catalogues ... and did find a star in my capture that was not there in Aladin? A star around mag 16-17.
So checked some more online. In the POSS2 data it was also not there. Checked for minor planets and variable stars and also there, not there.
Checked for recent novae in UGC 12188 and again, nothing.
Could it be that I ... ?
Nope. Because when I checked for supernova, it popped up: a supernova called SN 2021ucg (https://www.wis-tns.org/object/2021ucg), discovered on 25 July 2021. So I am 2 and half months too late
But nevertheless it feels like a real discovery for me. Capturing something that is nowhere on the current maps. Ah well, there is always a next time
Resolution: 0.486 arcsec/px
Meade LX 200 8" f/10 ACF (2028mm actual length)
