Noes:

1. Star #1 is saturated but it has a reliable Tycho-2 magnitude of
V=10.42+/-0.04.

2. EG Lac has not yet been positively identified. However on two POSS-II
plates exposed in 1993 there is a brighter object not apparent on other
images. This is at the approximate position of 22h 50m 38.9s +55d 14' 52".
On deeper POSS-II exposures this object is seen at about magnitude 21.5.
