SGR 1900+14
     K. Hurley, Space Sciences Laboratory, University of
California, Berkeley; T. Cline, Goddard Space Flight Center, NASA;
and E. Mazets and S. Golenetskii, Ioffe Institute, report:  "The
extraordinary KONUS burst reported by Cline et al. (IAUC 7002) has
been observed and triangulated with Ulysses.  The annulus of
possible arrival directions is indeed consistent with the position
of this soft repeater (IAUC 7001).  The 5.1-s periodicity is
clearly detected in the Ulysses data for 300 s following the burst
and in another event that followed it about 6 hr later.  A light
curve may be viewed at http://ssl.berkeley.edu/ipn3/newdata.html."

     E. Halderson, T. Shefler, M. Modjaz, J. Y. King, W. D. Li,
R. R. Treffers, and A. V. Filippenko, University of California at
Berkeley, report their discovery of an apparent nova during the
course of the Lick Observatory Supernova Search (cf. IAUC 6627)
with the 0.8-m Katzman Automatic Imaging Telescope (KAIT).  The
nova was found and confirmed on unfiltered images taken on Aug.
31.4 (mag about 16.6) and Sept. 1.3 UT (mag about 16.5).  The
object is located at R.A. = 0h42m39s.29, Decl. = +40o51'10".3
(equinox 2000.0), which is about 28".5 west and 44".7 south of the
nucleus of NGC 221 (the satellite galaxy of M31).  A KAIT image
obtained on Aug. 27.3 UT did not show a star at the position of the
nova (limiting mag about 19.0).
     S. Benetti, Telescopio Nazionale Galileo, La Palma; and T.
Pursimo and P. Heinamaki, Tuorla Observatory, confirm the presence
of a new object of magnitude R = 15.87 +/- 0.03 located 28".5 west
and 45".1 south of the nucleus of NGC 221, on an R frame taken with
the Nordic Optical Telescope at La Palma on Sept. 1.12 UT.
