Based on color correction made available by the Rc band image the earlier V
band magnitude estimate of the possible nova in Oph has been revised to the
following:
1/26/02
V = 9.19 +/- 0.05, 12:39 UT
Rc = 8.67 +/- 0.07, 12.44 UT
Comparison stars:
TYC 6248 1077 1, V = 9.94, B-V = .573, Rc = 9.63
TYC 6248 794 1, V = 9.77, B-V = .166, Rc = 9.68
The Rc magnitudes are derived from the B-V color of the star. The estimated
error in Rc relative to V is 0.03 mag. The check star used was TYC 6248 291
1, V = 10.43, B-V = 1.00, Rc = 9.88. MIRA software was used in the reduction
of the magnitudes.
I forgot to mention this in an earlier e-mail, I compared the image of the
field to SERC DSS1/ST5c1 plate and the object is not present on the DSS
plate.
