SN 2001ib was discovered independently  by two U.K. Supernova hunters, M. Armstrong and R. Arbour, on  Dec. 7.8 2001 in the evening sky .  The discovery location is at: R.A. = 22h15m38s.72, Decl. = +37d17m56.0s (2000.0), which is about 10" west and 1" north of the nucleus of the apparently spiral galaxy NGC 7242.  Discovery Reference IAUC 7768

Comet C/2000 SV74 (Linear)

Comet C/2000 SV74 was imaged twice during the evening with separation of nearly 2 hours. Comet lay on the border between Cassiopeia and Lacerta.  As at 2001-12-14, the comet was located around 3.74 AU from the Sun, in a position approximately midway between the orbits of Jupiter and Mars.   Magnitude was estimated to be around +15.
