Notes:

1. There is a close double at the position of the variable, the brighter
component about magnitude 15 and the fainter component about magnitude 
18 located 5 arcsec to the northwest. The fainter northwest component is
the variable, and the 15 magnitude companion is just that, an unrelated
companion. Extreme care will be needed to identify the variable in
quiescence.
