Notes: 1. The first two stars are saturated and their magnitudes and colours are only approximate. 2. There are two Tycho-2 stars in this field that extend the sequence at the bright end. One is at 06h 47m 32.4s +28d 11' 42" with V=8.58+/-0.02 and B-V=1.20, the other is at 06h 47m 45.7s +28 10' 16" with V=10.96 +/-0.08 and B-V=0.30. 3. There are four previous sequences for this variable, namely AAVSO chart 0641+18(f) dated January 1999, BAA VSS chart 042.01 dated March 1981, RASNZ chart 705 dated January 1982 and Misselt, PASP, 1995. Correspondencies are as follows. Only stars with an ID# form part of this new sequence.
