V418 CAS (=Q1989/90)
M.Collins, Sandy, reports that this mira variable located at:
RA 01h09m36s DEC +61 55 (1950) was recorded at about mag 10.5-11
on Nov 23.9UT using K2415 film. This is exceptionally bright as the
GCVS range is 14.6-[20p.

V1819 CYGNI
This nova located at RA 19h52.7m DEC +35 33'(1950) is now very
faint but recent estimates suggest that there may be an
identification problem. Star 'W' has been added under revision
891203. It is located 82mm from top and 117mm from right edge on
photograph by R.Chanal of 860902 on back cover of TA272.
A new photograph at prime focus would be helpful to check the ID.

RZ SGE
G.Poyner, Birmingham, queries faint comparisons on the sequence
for RZ Sge. His estimate is followed by the chart value:
K 14.7, 15.0; L 14.9, 15.3; M 15?, 16.3. Any comments?
