SUPERNOVA 1998cp IN MCG +9-21-11
     M. Schwartz, Cottage Grove, OR, reports his discovery of
an apparent supernova (mag 18.0) on an unfiltered CCD frame taken
with the 0.35-m Tenagra I automated supernova patrol telescope on
June 21.27 UT.  The candidate is located at R.A. = 12h31m52s.3, Decl. =
+52d23'39" (equinox 2000.0), which is 3" east and 24" south
of MCG +9-21-11 (CGCG 270-008).  The object is also present
on frames taken on June 22.29 and 27.25, fading by some 0.5 mag apparent
by the latter occasion.  The limiting magnitude of the exposures was about
19.  The object does not appear on either the first or the second Palomar
Sky Survey scans, and it is also absent from the USNO-A1.0 catalogue.


METEORS
     I. Sato, National Astronomical Observatory, Tokyo, reports that several
observers in Japan observed a sudden meteor shower around June 27.6 UT.
K. Usuki (Aizu, Fukushima) reported seeing 40-50 meteors per hour at the
peak, even through 80-90-percent cloud cover; the radiant was between eta
UMa and alpha Boo.  Y. Yabu (Omihachiman, Shiga) reported that an (unknown)
observer in Okinawa saw "a couple" of meteors per minute, the radiant being
in Corona Borealis.  Y. Kushida (Yatsugatake, Yamanashi) recorded numerous
meteors by VHF radio during June 27.58-27.67 UT.  T. Hamane (Misato
Astronomical Observatory) reported many bright meteors with trains.
