There are three additional bright stars in this field with accurate Tycho-2 photometry: 19h 10m 08.3 +29d 07' 26" 9.46+/-0.02 19h 10m 38.9 +28d 59' 24" 10.22+/-0.04 19h 10m 30.2 +28d 59' 21" 10.46+/-0.04 2. This preliminary single night sequence is expected to have errors of +/-0.02 mag. 3. The variable has not been found in quiescence, but there is a faint magnitude 19 object at the D&S position, which is given in the title block above. Bruce Sumner 5 April 2002
