SUPERNOVA 2000cr IN NGC 5395
     Marco Migliardi and Alessandro Dimai report their discovery of
a supernova (mag about 17) on CCD images taken on June 25.90 and
25.94 UT with the 0.5-m Ullrich telescope at the Col Drusci
Observatory in the course of the CROSS program.  SN 2000cr is
located at R.A. = 13h58m38s.37, Decl. = +37o26'12".4 (equinox
2000.0), which is 2" east and 44" north of the center of NGC 5395.
Nothing was visible at this location on a CROSS image obtained on
June 3 (limiting mag 18.5).
     W. Li, University of California at Berkeley, reports that SN
2000cr is present (mag about 16.7) on an unfiltered KAIT CCD image
obtained on June 26.2 UT.  Li provides position end figures for the
supernova:  38s.37, 12".9, which he notes to be 4".2 east and 45".2
north of the nucleus of NGC 5395.  Li adds that NGC 5395 is
interacting with NGC 5394.  A KAIT image of the same field taken on
June 21.2 showed nothing at the position of SN 2000cr (limiting mag
about 19.0).
     S. Jha, P. Challis, and R. Kirshner, Harvard-Smithsonian
Center for Astrophysics, report that a spectrum of SN 2000cr, taken
by M. Calkins on June 26.17 UT with the F. L. Whipple Observatory
1.5-m telescope (+ FAST spectrograph), shows it to be a type-II
supernova at an early epoch.  The spectrum exhibits a blue
continuum with broad P-Cyg H and He features.  Narrow superimposed
H-alpha emission yields a recession velocity of 3350 km/s for the
host galaxy.


SUPERNOVA 2000cq IN UGC 10354
     T. Puckett, Ellijay, GA, reports that he detected SN 2000cq
(cf. IAUC 7442) independently on an unfiltered CCD image taken on
June 3.127 UT, when it was at mag 19.6, and he provides the
following precise position for the supernova:  R.A. = 16h21m21s.33,
Decl. = +40o48'09".9 (equinox 2000.0).


V1493 AQUILAE
     R. Novak, Copernicus Observatory, A. Retter, Keele University;
and Y. Lipkin, Wise Observatory, report:  "We performed CCD optical
photometry of V1493 Aql (N Aql 1999 No. 1) during twelve nights in
1999 July-August.  The light curve is modulated with period 0.156
+/- 0.001 day.  The folded data suggest the presence of eclipses
with an amplitude of 0.014 mag."
