SUPERNOVA 1988I IN ANONYMOUS GALAXY
     C. Pollas, CERGA Observatory, Caussols, reports the discovery
of a supernova in an anonymous galaxy located at R.A. = 10h18m17s, Decl. =
+35 54.7 (equinox 1950.0).  IIIa-J Schmidt plates exposed Mar. 7.85
and 11.91 UT show the object at mag about 19 and located 5" east and 1"
north of the galaxy's center.


SUPERNOVA 1988A IN M58
     E. M. Sadler, Anglo-Australian Observatory; and S. M. Simkin,
Michigan State University, report the following photometry obtained
with the 1.5-m telescope (+ TI CCD and Gunn vgri filters) at Cerro
Tololo Interamerican Observatory, along with transformations to the
Johnson system (after Kent 1986, P.A.S.P. 97, 164):  Jan. 23.37 UT,
r = 14.49, (g-r) = -0.19, (v-g) = -0.47, (r-i) = -0.56, V = 14.35-
14.40, R = 14.01-14.06, (B-V) = 0.00; Jan. 24.38, 14.49, -0.14,
-0.42, -0.58, 14.38-14.42, 14.00-14.05, +0.03; Jan. 25.35, 14.54,
