Subject: [vsnet-obs 0] SN2002ap

We have observed SN2002ap using the Caltech Astronomy Department's 14"
telescope, in Meade filters which approximate V and R.  Conditions were
relatively poor, with significant cloud cover and sky glow from Pasadena,
CA.

Attached are .gif files of the observations, each image is a combination
of 3 x 2 minute exposures.  Only dome flats were used in the reduction,
hence the gradient across the frame.  SN is marked by green cross.  Star 1
(GSC1205.1059) was used as reference for crude aperture photometry, taken
to be V=13.3, R=12.9.  Corresponding magnitudes for Star 2 (GSC1205.789)
were measured at V=13.9, R=13.6.

With this reference, SN2002ap is measured at V=13.1, R=13.2.

Approximate mean exposure time in V was UT 02:46:16, 2002-2-2.
Approximate mean exposure time in R was UT 02:34:07, 2002-2-2.
