Notes: 1. There is a bright Tycho-2 star in the southwest corner of this field with a reliable magnitude of V=9.64+/-0.03. 2. There is a Preliminary AAVSO 'd' chart dated 7/1995 with a photoelectric V sequence by Richard Stanton. The only discrepancy is star #3 for which Stanton gives 125 rather than 126. 3. Two other sequences have been prepared from Henden's photometry. One by Robert Modic (vsnet 1841) in May 1999 and another by Reinder Bouma (vsnet-chat 4180) in April 2001. In both cases the stars chosen to form the sequence are very similar to the sequence presented here. All three sequences can be used independently. Bruce Sumner 15 April 1999 Revised 17 April 2001
