6.67, 13.1 (Y.Takenaka, Japan).
AL COM
Recent results show that the star has undergone a major fade
followed by a recovery. Fluctuations appear to be over a short
time scale and observations are therefore recommended several times
each night:

Nick James, Chelmsford has e-mailed an image obtained on
1995 May 3.8UT (0.30-m reflector+CCD) which shows the star near
this initial minimum at approximately magnitude 16.5. He has
again measured the position to check identification:
1995 May 3 RA 12h32m25.83s DEC +14 20'42.9"(2000)
This is around 0.1" from the position he obtained on 1995 Apr 6
and which appeared on E944 and VSC 61.
VARIABLE IN CEPHEUS ON 'LD' PHOTOS (=Q1995/033)
Discovery details for the above object appeared in
'The Astronomer', Vol 31 No 372 [1995].
Gareth Williams, Minor Planet Center, USA reports that the object
is recorded on the recently received Digital Sky Survey at V=14.
He obtains a precise position from the PSS I plate [epoch
1954.595, 15 comparison stars from GSC, mean residual of fit
0.2"]:
RA 21h57m26.08s DEC +64 12'48.9"[2000].
MV LYRAE
S.Yu Shugarov (Sternberg State Astronomical Institute) and
V.I.Marsakova (Odessa State University) report observation of
MV Lyrae possibly returning from low to its usual bright state:
variations (V): April 25 15.56-16.14
                April 27 14.68-14.75
