SUPERNOVA 2001ib IN NGC 7242
IAUC 7768 reports the independent discovery of an apparent supernova by
Mark Armstrong and Ron Arbour. The object (mag 15.3) is located about
9"-10" west and 1" north of the center of NGC 7242. The IAUC states that
the object was reported on "unfiltered CCD images taken by M.
Armstrong, Rolvenden, Kent, England, on Dec. 7.808 and 7.844 UT (0.35-m
reflector) and by R. Arbour, South Wonston, Hampshire, England, on Dec.
7.786 (0.3-m reflector).  Armstrong measures SN 2001ib to be at R.A. =
22h15m38s.72, Decl. = +37o17'56".0 (equinox 2000.0); Arbour provides
position end figures 38s.43, 56".0.  T.  Boles obtained confirming
images on Dec. 7.824 and 7.828.  Nothing is present at this location on
Armstrong's images taken on Aug. 20 (limiting mag 19.5) and Nov. 15
(limiting mag 19.0) or on a red Palomar Sky Survey image taken 1986 Oct.
1 (limiting mag 20.8)."

NGC 7242 is in Lacerta and this is a very convenient early evening
object at the moment almost overhead from the UK at 5pm. Observations
are strongly encouraged.

This makes 32 discoveries for Mark and five for Ron. Our congratulations
to both observers on this further success.
