THE ASTRONOMER Electronic Circular No 14 1987 Mar 29  16.24UT.

TAV 0723-03
Further to the announcements on E11 and E13, several observers have
reported that this object has remained constant at around mag 9.2.
The earliest photos which show the object are by R.McNaught on
Feb 18, thus the star has been virtually constant for many weeks
and this appears to cast doubt on the proposal that it is a
hitherto uncatalogued mira. Further daily results are needed.
Supernova 1987A
Cablegrams have been received from M.Collins, observing for the UK
Nova/Supernova Patrol, and temporarily in Wodonga, Australia. He
reports the following recent magnitude estimates for Supernova
1987A:
Mar 21.68UT, 4.2; 22.41, 4.2; 23.45, 4.2; 24.39, 4.2; 25.42, 4.2,
26.39, 4.2. (7x50B).
On Mar 24 he described it as yellow.
Outburst of CH UMa
Steven Lubbock reports the major outburst of this star as follows:
Mar 20.857, (14.0; 21.873, 13.0; 25.852, 11.6.
The variable, which is located at: RA 10h03m.15 DEC +67 47'(1950)
was mentioned on E-circular 7 as flickering at around mag 13 on
Feb 20, evidently a prelude to the current major outburst.
Further daily estimates would be welcomed.
