Wiggins, Tooele, UT, USA, reports his discovery of a possible supernova (mag ~17.0) on an unfiltered CCD frame taken 2020 Feb 26 10:01:22 UT using a 0.35-m f/5.5 reflector near Erda, UT, USA. The new object is located at R.A. 20h37m10.72s, Decl. +66°06'12.80" (equinox 2000.0), about 22” SW of the center of NGC 6952. Wiggins notes that nothing was visible at this position on an image taken the day before, however the seeing then was very poor.

Comparing with spectra using SNID ( Blondin, S. & Tonry, J. L. 2007. ApJ, 666, 1024) gives a good match to several type IIP supernovae around 25 days after maximum

Object coordinates updated according to AT-report 65522 of Group GaiaAlerts
Previous RA, DEC: 20:37:10.720, +66:06:12.80 (309.294667, +66.103556)
Updated RA, DEC: 20:37:10.550, +66:06:10.66 (309.293958, 66.102961)

Note the redshift was changed in error. It should be 0.0048 as originally set.  Administrator please correct - thanks
