Notes:

1. There are two bright stars in this field that were to bright to be 
included in the photometry. The brighter one, in the north of the field, 
has a reliable Tycho-2 magnitude of 9.41 +/-0.02. The other, in the south 
of the field, has a more approximate Tycho-2 magnitude of 10.7 +/-0.1.

2 Also known previously as var61 Her.

3 For information on the discovery of this variable see IBVS 4578.

4. Varies at minimum between about V=18.7 and V=19.3.
