Zhangwei Jin(Ningbo, Zhejiang, China) and Xing Gao (Urumqi, Xinjiang, China), report the discovery of a possible supernova (mag approximately 18.6) on two 40-s survey images (limiting mag about 19.5)taken by Xing Gao in Xingming ObservationSky Survey(C42) around Mar.15.95301 and 16.95425 UT,2013. using an unfilted CCD ( + Celestron C14 Schmidt-Cassegrain telescope D=350-mm @f/6.9 ).the new object approximately located at R.A. =15h 54m 56s.68 Decl.=+43°03'07".7(equinox 2000.0). Which is about 22.8" west and 32.3" south of the center of the PGC 59251. Nothing is visible at this position on archival images taken on Feb.26,2013.

L. Elenin (Lyubertsy, Russia) and I. Molotov (Moscow, Russia) confirm an apparent supernova PSN J16545668+4303077 in UGC 10610. Object visible on 3x300sec images remotely taken at ISON-NM Observatory (Mayhill, NM, USA) with 0.45-m f/2.8 telescope + CCD (KAF09000) on Mar. 17.447, 2013. Object located at 16h 54m 56s.69 +/- 0".06, +43d 03' 07".5 +/- 0".05 (UCAC-4) with magnitude 18.6U (mag. limit ~20.7m). Nothing is visible at this position on the POSS and POSSII images.
