This is a preliminary sequence, based on only a single nights data. 2. There is a bright star just off the edge of this field with an accurate Tycho-2 magnitude of V=9.02+/-0.01 and another on the northern egde with a magnitude of V=10.58+/-0.04. 3. This variable was discovered by Dahlmark and was originally called LD 197. Dahlmark found two bright outbursts, in 1968 and 1993, at about magnitude 12.5p. On DSS images this variable is as faint as magnitude 20p. Bruce Sumner 23 May 1999 Revised 12 December 2000
