  Supernova 2002bo (Type Ia), IAUC 7847 discovered March 9.08, 2002 by Paulo Cacella; Yoji Hirose Found in NGC 3190 at R.A. = 10h18m06.52s, Decl. = +21d49m41s.2 Located 11".6 east and 14".2 south of the center of NGC 3190 (Discovery image) (Remanzacco obs image). Mag 14.6 and rising, Type Ia (CfA spectrum) (References: IAUC 7848, 7849)) Located 258" west and 108" south of the center of NGC 3190 (= M74)

  Photos of SN 2002bo have been taken by Zorko Vičar and Matija Kastelic 11th of March 2002, at 22:54 UTC with CCD ST7 (no Filter), exposure:80s, telescope SC 10", f/6.3", city Ljubljana, state Slovenia.
