Since 1987 we have provided the community with rapid notification of
astronomical events via our e-circular service. Circulars are sent via
e-mail at the rate of around 150 per year. An example of one of our circulars
is given here. To get the up to the minute news you will need to

V1057 CYGNI
Further estimates: 1995 May 2.931, 13.3 (Tonny Vanmunster, Belgium)
3.13, 13.1 (Michel Verdenet, France); 4.07, 13.2 (Vanmunster);
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
