Notes:

1. Star 1 is saturated, and its magnitude and colour are approximate. It
does have a reliable Tycho-2 magnitude of 10.59+/-0.05.

2. There as an AAVSO 'e' chart dated 02/92 which contains a photoelectric
sequence. The following stars are common to both sequences:

               ID   AAVSO   Henden
                      V        V
               1     106    10.648
               2     119    11.882
               3     131    13.166
               4     138    13.784
               6     147    14.736
               7     150    14.987 
               8     159    15.866

3. Found to have superhumps with a period of about 80 minutes during a 
superoutburst in 1991 by O'Donoghue, 1991 MNRAS, 250, 363 and thus 
shown to be an SU UMa-type dwarf nova. Varies at minimum between 
about V=17.3 and V=18.0.
