POSSIBLE OUTBURST OF AL COM (=Q1990/10)
W.Worraker, Didcot, reports a possible outburst of AL Com
(=Nova Com 1961)= Rosino's Object located RA 12h29.9m DEC+14 37
(1950). Precise details are withheld to avoid bias but
the catalogued range is 13.0-20p. Confirmation is urgently
needed.
Rosino found the star on a plate of 1961 Nov 17 at mag 14
(IAUC 1782) and later the star was also found in outburst on a
plate of 1892 Apr 26 at mpg=14.3.(Ann.d'Ast 27,298,1964).
According to Variable Stars 20,277,1976 P.N.Kholopov mentions
the most recent  recorded outburst as 1975 Mar 8.
Vogt and Bateson published a new finder in As.Ap.Suppl.48,p395
based on the Palomar Sky Survey which does not appear to show
any other star very closeby to mag 20.
The current TA chart (rev 830403) should be adequate for
identification checks.
 
POS VAR NGC 3587 (=Q1990/7)
Various observers report no new or variable object in NGC 3587 as
suggested on E383 by Miablint.
