[vsnet-alert 3683] NGC 1097 BVRI sequence

[bas@mailhost.lowell.edu (Brian Skiff)]

     In re SN 1999eu in NGC 1097, just announced on IAUC 7304, here is a BVRI
photometric sequence suitable for CCD observations.  This is one of the
excellent sequences published by Hamuy & Maza (1989 AJ 97,720), which are of
"secondary standard" quality.  The paper, which can viewed using the ADS
Web site, also contains charts.  The stars below can also be used to make a
local zero-point adjustment to USNO-A magnitudes for fainter stars.
