POSSIBLE OCCULTATION OF AGK3 07 0061 = BD +07 72.
Andrew Elliott, Reading, advises us that the asteroid 139 JUEWA of
mv=12.5 may occult AGK3 07 0061 on 1990 October 22 and recommends
that the star be monitored between 18.40-19.00UT. The star's
position is: RA 00h31m55.84s DEC +07 44'37.19"(1950) and is of mag
10.0pg, Sp=F5.
The event may be visible from the south of England but it is
suggested all European e-circular subscribers monitor the star.
The magnitude drop is expected to be 3.5mags and maximum duration
could be 12.1secs.
SUPERNOVA 1990ae IN ANONYMOUS GALAXY
J. Mueller reports her discovery of a supernova in an anonymous
galaxy at R.A. = 0h20m.3, Decl. = +6 33' (equinox 1950.0). The
supernova (mag about 18) is located 13".4 east of the galaxy
nucleus. The red discovery plate was taken by Mueller and J. D.
Mendenhall on Oct.15 UT with the 1.2-m Oschin Telescope in the
course of the second Palomar Sky Survey.

NOVA IN M31
J. Bryan, Georgetown, TX, reports his discovery of a nova in M31,
located at R.A. = 0h40m20s, Decl. = +41 40'.5 (equinox 1950.0),
or about 296" east and 87" north of the galaxy's centrer Bryan
provides the following B magnitudes: Oct. 11.18 UT, [19.4; 13.16,

TY SAGITTAE
Gary Poyner, Birmingham, reports that he has observed this star,
which is in the field of RZ Sge, on 20 nights 1990 May 22 - Aug 29
and finds a range of 13.9-14.7. On 1989 Aug 28 he made it 13.6. The
star, located at: RA 20h01m21s DEC +16 53.1'(1950), is given as
13.4pg and constant in the latest GCVS. Other sources have listed
it as of type UG? Does anyone have current or historical information
on this star please?
