Notes:
1- Star #1 is saturated and its magnitude is approximate.
2- There are three bright stars with reliable Tycho 2 magnitudes 
in this field. They are given for guidance only, since they fall well
outside the maximum range of this variable.

A  18 58 50.97 +30 10 48.6 =6.80V
B  18 58 13.92 +30 10 52.3 =9.32V
C  18 58 24.18 +30 15 48.2 =10.21V
