Notes:
1. Zero point errors are expected to be 0.02 magnitudes or better.
2. Gaps in the sequence can be filled by ASAS-3
A  00 24 44.6 +12 12 46  V=11.158 +/- 0.02  GSC 599 255
B  00 24 36.8 +12 11 49  V=12.057 +/- 0.02  GSC 599 184
C  00 25 09.5 +12 08 58  V=12.207 +/- 0.02
D  00 25 45.8 +12 17 00  V=12.589 +/- 0.02
3. Star D has a 15th mag companion 15"SW and should be used with care.
