COMET BRADFIELD (1979c)
     D. Herald, Kambah, near Canberra, reports the following
precise positions:

U SCORPII
     Y. Kozai, Tokyo Astronomical Observatory; and J. Mattei, American
Association of Variable Star Observers, communicate the following
observations of the outburst of this recurrent nova (but see
also IAUC 3341 and 3343):

     1979 UT         Mag.    Observer
     June 23.550     8.7*    Hiroaki Narumi
          23.628     8.8     Yoshiyuki Kuwano (Tri-X film)
          24.906     9.4     Tom Cragg (Anglo-Australian Obs.)
     *incorrectly given as 6.7  on the telegram

     C. Whitney, Center for Astrophysics, provides the following
photoelectric observations obtained with the 40-cm reflector at
Harvard's Agassiz Station: June 26.16 UT, V = 10.30, U-V = -0.71, B-V
= -0.13, V-R = +1.15, V-I = +1.93.


NOVA IN NGC 5272
     B. Mayer, PROBLICOM Sky Survey, reports that Steve Wasserbaech
and Jerry Johnson, Salt Lake City, have discovered a novalike star
in the globular cluster NGC 5272 = M3.  The star, located 22" due
south of the cluster center, was observed at V ~ 12 (+/- 0.5) on May
31.  It was ~ 2 magnitudes fainter in April, according to photographs
taken both by Mayer and Wasserbaech.  On June 25 its V magnitude
was 15 +/- 0.5, according to W. Liller, who also observed the
star with a Reticon spectrograph at the Mount Hopkins Observatory.
Its spectrum from 4500 to 7000 A appears typical of a nova near
maximum with only Balmer lines visible in absorption.
