Just to clarify, my magnitude estimates for 2/21 were
15.10 and 14.90.
Sorry for the confusion. Here is my original post:
I have made a new magnitude estimate for SN1999aa, as follows:
est.
ref. star cat. ref. mag. SN1999aa mag.
GSC-1391-0558 HGSC 15.36 15.10
GSC-1391-0181 HGSC 14.42 14.90
This estimate was made with a ten min. exposure using an ST7 ABG
camera at -15 deg. C and 6" AP refractor in fair-good conditions
from Valencia, California at approx 04:57 U.T. on February 21,
1999. Photometry by CCDSoft.
