Notes:

1. The three brightest stars are saturated, and their magnitudes and 
colours are approximate. Star #1 has a reliable Tycho-2 magnitude of 
9.98V +/-0.03. Stars #2 and #3 should be used for guidance only until
accurate magnitudes are obtained.

2. LX And is the northern component of a double star. The southern
component has a magnitude and colour of V=16.250+/-0.066
B-V=0.970+/-0.074. The separation of the components is 10.0 arcsec. 

3. LX And was originally classified as an RV Tauri type in 1982, this 
variable star has been determined to be an UGSS-type dwarf nova by 
Uemura 2000, IBVS 4831.

4. LX And fluctuates around V=16.7 to V=17.1 at minimum, as determined 
from measurements obtained on four separate nights.
