SUPERNOVA 2001ak IN UGC 11188
     M. Schwartz, Cottage Grove, OR; and W. D. Li, University of
California at Berkeley, on behalf of LOTOSS (cf. IAUC 7514), report
the discovery of an apparent supernova on unfiltered images taken
with the 0.5-m Tenagra III automated telescope on Apr. 1.5 (mag
about 18.4) and 3.5 UT (mag about 18.1).  SN 2001ak is located at
R.A. = 18h17m31s.44, Decl. = +18o54'00".8 (equinox 2000.0), which
is about 24" east and 12" south of the diffuse nucleus of UGC
11188.  An image taken by the Katzman Automatic Imaging Telescope
on 2000 Oct. 8.3 showed nothing at this position (limiting mag
about 19.0).


SUPERNOVA 2001al IN ANONYMOUS GALAXY
     A. Gal-Yam and D. Maoz, Tel Aviv University, report for the
Wise Observatory Optical Transients Search (cf. IAUC 6917, 7055)
their discovery of the first supernova (R about 21.1) from the
second phase of this project on unfiltered CCD images taken by H.
Mendelson on Mar. 26 with the wide-field SITe camera mounted on the
Wise Observatory 1-m telescope.  SN 2001al is located at R.A. =
15h44m51s.74, Decl. = +36o07'29".0 (equinox 2000.0), which is in
the field of the galaxy cluster Abell 2122 (z = 0.065).  No
apparent host galaxy is detected.  SN 2001al was invisible in
images obtained on 2000 Aug. 30 (limiting mag R about 22.0).  The
new object was confirmed on CCD images taken by J. Dann on Mar. 28
with the Tektronics CCD camera mounted on the same telescope.

     A. V. Filippenko, University of California, Berkeley; A. J.
Barth, Harvard-Smithsonian Center for Astrophysics; and D. C.
Leonard, University of Massachusetts at Amherst, report that
inspection of a CCD spectrum (range 390-880 nm) obtained on Mar. 29
UT with the Keck-I telescope reveals that SN 2001al is of type Ia,
about 1 month past maximum brightness.  The estimated redshift,
0.065-0.07, is consistent with that of the cluster Abell 2122.
