PSN J04424114+1834597   2012 12 20.6121*  04 42 41.14 +18 34 59.7  17.2 V    5W   0N            1 0


2012 12 20.6121

This PSN in LEDA213292 (mag.= 17.2V) was discovered by M. Koishikawa, Sendai Astronomical Observatory using 1.3-m f/4.85 reflector + CCD under the limiting magnitude = 19. Offset from host galaxy must be correct as "19W, 0N" not "5W, 0N", sorry. Nothing is visible at this location on POSS2/UKSTU (red, 1991 Oct.11, limiting mag.= 19.0). Koishikawa's discovery image was posted at: http://space.geocities.jp/yusastar77/supernova/PSNinLEDA213292_121220.htm Communicated by Toru Yusa, Osaki.

This PSN was clearly seen on two CCD images (5 min exposures each ) taken remotely with 0.32m, f/8 Astrofraph + STL-6303E CCD camera (T18, iTelescopr.NET, Nerpio, Spain). Mag was 16.3V.

Mag.=16.4U, position end figures 41s.12, 59".8 (USNO-B1.0), remotely using the 0.25-m f/3.4 astrograph + CCD (SBIG ST-10XME) at RAS observatory near Mayhill, NM, U.S.A. (H06). Position and magnitude were measured on an image composed from 3-frames which were taken by each 120-seconds exposure under the limiting magnitude = 18.5. Observer T. Yusa, Osaki, Japan.

L. Elenin (Lyubertsy, Russia) and I. Molotov (Moscow, Russia) confirm an apparent supernova PSN J04424114+1834597 in UGC 3447. 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 Dec. 21.0689. Object located at 04h 42m 41s.11 +/- 0".09, +18d 34' 59".9 +/- 0".08 (UCAC-4) with magnitude 16.5U (mag. limit ~19.5m). Nothing is visible at this position on the POSS and POSSII images.
