D. Grennan, Raheny Observatory, Dublin, Ireland reports his discovery of an apparent supernova in IC2166 (Galaxy RA: 06 26 55.2 DEC: +59 04 41.0) (Mag. 16.2) on unfiltered CCD images (limiting mag + 19.8) taken on Aug. 22.00889 UT using a 0.35-m f/4.9 Schmidt-Cassegrain telescope (+ SBIG ST8-XME CCD camera) in the course of his supernova patrol. The new object appears at the following J2000 co-ordinates, RA: 06 26 51.01 DEC: +59 05 02.6). This places the new object 32".3(West) and 21".6(North) of the core of IC2166

D. Denisenko, V. Lipunov (SAI MSU), V. Yurkov, E. Sinyakov (Blagoveschensk Educational State University) report on behalf of a larger MASTER collaboration: PSN J06265101+5905026 was found on the unfiltered survey image (60-sec exposures) taken by MASTER-Amur robotic telescope (0.40-m f/2.5 reflector + 16 Mpix CCD) on 2012 Aug. 19 at 18:35:30 UT (2.3 days before the discovery images posted at TOCP). Position end figures are 51.06s, 02.6", unfiltered magnitude on Aug. 19.775 UT is 15.8+/-0.1. Nothing is visible at this position on MASTER-Amur image of 2012 Mar. 30. UT (limiting magnitude 17.9). Comparison of Aug. 19 and Mar. 30 MASTER-Amur images is posted at http://master.sai.msu.ru/static/OT/PSNJ06265101+5905026-MASTER.jpg
