SUPERNOVA 1993ae IN UGC 1071
     C. Pollas, Observatoire de la Cote d'Azur, reports his discovery
of a supernova of mag V = 16.5 on two films taken Nov. 7.92 and
7.97 UT.  The object is located at R.A. = 1h27m16s.08, Decl. =
-2o14'05".5 (equinox 1950.0); the galaxy's center is located at end
figures 15s.00, 29".9.  Nothing was found at this position to mag
21.5 on films taken Oct. 20.07 and 20.11.  A nearby star (V about
14) is at end figures 15s.42, 15'24".6.
     E. Cappellaro, European Southern Observatory; and A. Bragaglia,
Osservatorio Astronomico di Bologna, report:  "On Nov. 11.2 UT, we
obtained a spectrogram (range 340-910 nm, resolution 7 nm) of SN
1993ae, using the ESO 1.5-m telescope and the Boller & Chivens
spectrograph.  The spectrum is very similar to that of a normal
type-Ia supernova about 10 days after maximum.  In particular,
strong absorptions are measured at 386.2, 452.4, 519.5, 580.8, and
626.5 nm.  The last of these, attributed to Si II 635.5 nm,
indicates an expansion velocity of about 10 000 km/s."

     Y. Tanaka, Institute of Space and Astronautical Science, on
behalf of the ASCA Team, communicates:  "GRS 1009-45 (IAUC 5864,
5886) was observed with ASCA on Nov. 10 UT.  The source was found
in the BATSE error box, and its location is determined as R.A. =
10h11m26s.2, Decl. = -44o48'23" (equinox 1950.0; systematic error-
circle radius 1').  The spectrum is very soft (kT about 0.6 keV if
approximated by a thermal spectrum) and accompanied by a hard tail,
which is very similar to GS 2000+25 and GS/GRS 1124-68.  The source
is still very bright, with a flux of about 2 x 10E-8 erg cmE-2 sE-1
or 0.8 Crab in the range 1-10 keV, of which the flux below 3 keV

     D. D. Balam reports a position for this object, obtained with
the 0.5-m reflector (+ CCD) at Climenhaga Observatory (University
of Victoria):  R.A. = 5h41m36s.99, Decl. = +63o20'57".2 (equinox
1950.0; mean error 0".5).  The nucleus of the host galaxy is at end
figures 38s.04, 24".3.
