Star #1 is saturated and its magnitude should be used with discretion. 2. There are two bright stars in this field that were not measured during the determination of this sequence. One is at 04h 02m 57.1s +42d 48m 19s and has a reliable Tycho-2 magnitude of 9.70+/-0.03 and the other is at 04h 03m 05.3s +42d 46m 43s and has a reliable Tycho-2 magnitude of 8.70+/- 0.02. 3. The variable is one of the components of a close double star, but it has not been determined which is the actual variable. The two components have the following single night photometry: Comp 1: V=15.846 B-V=0.460 Comp 2: V=17.196 B-V=0.672 I have tentatively identified the bright northern component, located 5 arcsec north of the fainter component, as the variable.
