(724) HAPAG = 1988 VG2
S. Nakano, Center for Astrophysics, has indentified this long-lost
minor planet with an object discovered by T. Hioki and N. Kawasato at
Okutama, Japan, on Nov. 8. There are no other identifications with
recorded minor planets since J. Palisa's original discovery in 1911.

SUPERNOVA 1988V IN ANONYMOUS GALAXY
R. Kirshner and E. Schlegel, Center for Astrophysics, report
that observations made at the F. L. Whipple Observatory by E. Horine
and R. Schild on Nov. 16 indicate that the object's spectrum
resembles that of a type-Ia supernova about 25 days past maximum light.
C. M. Gaskell, University of Michigan, writes: "Inspection of
unreduced CCD spectra (range 450-750 nm) taken by R. M. Wagner with the
2.4-m Hiltner telescope of the Michigan-Dartmouth-MIT Observatory on
Nov. 16 shows that this object is a type-Ia supernova a few weeks past
maximum (cz of the host galaxy is about 9600 km/s)."
V1118 ORIONIS (NSV 2229)
M. Verdenet, Bourbon-Lancy, France, reports that this irregular
nebular variable star (cf. IAUC 3924, 3935, etc.) has brightened,
being at mv = 14.0 on Nov. 15.94 UT.
