1986 EB
     C. and E. Shoemaker have discovered a fast-moving minor planet
on films exposed with the 0.46-m Schmidt telescope at Palomar, with
the following approximate positions available:

            1986 UT           R.A. (1950.0) Decl.     B

            Mar.  4.33247     12 17.0     +28 21     14
                  5.34444     12 10.1     +27 55
                  8.23229     11 50.7     +26 35


PROBABLE NEW COMET SHOEMAKER
     The Shoemakers also report their discovery of images of a
probable new comet on 0.46-m Schmidt films, the object appearing
diffuse with central condensation and m1 ~ 15.5, m2 ~ 17.

               1986 UT           R.A. (1950.0) Decl.

               Mar.  4.33247     12 14.4     +23 40
                     8.23819     12 04.7     +24 48


SUPERNOVA 1986C IN UGC 6697
     B. Leibundgut and B. Binggeli, European Southern Observatory,
La Silla, report their discovery of a supernova in the irregular
galaxy UGC 6697 (R.A. = 11h41.2m, Decl. = +20deg15', equinox 1950.0).  The
new object lies ~ 60" north and 60" west of the galaxy's center,
and on Mar. 5.2 UT was at B ~ 18.  A prediscovery record of the
supernova from Feb. 9.3 shows it to have been brighter then.  A
spectrum taken by W. Sargent and J. Steidel on Mar. 7.2 shows the
object to be a type-II supernova past maximum light.


PERIODIC COMET BOETHIN (1985n)
     Further total visual magnitude estimates:  Feb. 6.10 UT, 7.5
(C. Spratt, Victoria, BC, 11x80 binoculars); 9.10, 8.1 (Spratt,
0.08-m refractor); 28.05, 9.4 (J. E. Bortle, Stormville, NY, 0.32-m
reflector); Mar. 1.03, 9.6 (Bortle); 2.04, 9.7 (Bortle).
