Re: S10828 (AS Psc)

   S10828 was discovered by Richter from the Tautenberg plates taken on
1963 Sep. 14 and 17.  The second outburst was observed during 1980 Aug.
8-14.  The object seems to have been first considered to be a reccurent
nova in M33.  Richter notes the strong UV-excess during the outburst.

   Another outburst was observed in 1984.

  2445964.311   16.73
     5965.284   18.3
     5966.444  <18.9
     5968.333  <18.9

   Further outburst ob 1986 Dec. 5 (JD 46770.361) at B=19.1.  AS Psc is
now regarded as a galactic dwarf nova having a long outburst interval
(Sov. Astron. Lett. 13(3), 1987).

   I believe there was a positive photographic detection in the VSOLJ
database -- will check from now.

   The VSNET chart is available, approximating the V-magnitudes:
