SUPERNOVA 1999cq IN UGC 11268
M. Modjaz and W. D. Li, University of California at Berkeley,
on behalf of the Lick Observatory Supernova Search (cf. IAUC
6627, 7126) with the 0.8-m Katzman Automatic Imaging Telescope
(KAIT), report the discovery of an apparent supernova in UGC 11268.
The supernova was discovered on an unfiltered images taken on June 25.4 UT
(mag about 15.8), and confirmed by earlier observations on June
22.4 (mag about 15.8) and 19.4 (mag about 15.9). The new object is
located at R.A. = 18h32m07s.10, Decl. = +37o36'44".3 (equinox 2000.0),
which is 1".5 east and 4".1 south of the nucleus of UGC 11268. A KAIT
image of the same field on June 15.4 UT (limiting mag about 19.0)
showed nothing at the position of the supernova.
NOVA IN NGC 6822
J. Y. Wei, D. W. Xu, Q. Y. Qiao, Y. L. Qiu and J. Y. Hu,
Beijing Astronomical Observatory (BAO), report the independent
discovery by the BAO Supernova Survey of the object reported on
IAUC 7208. The observations with the 0.6-m telescope at Xinglong
showed the apparent nova on June 23.69 and 24.72 UT at unfiltered mag
about 18.
V382 VELORUM
Additional photometry by A. C. Gilmore with the 0.6-m f/16
reflector at Mt. John University Observatory (same reference star data
as on IAUC 7196): June 9.488 UT, V = 6.41, U-B = -0.92, B-V = -0.07,
V-R = +1.34, V-I = +0.94, airmass = 1.63; 10.368, 6.46, -0.93, -0.09, +1.34,
+0.93, 1.12; 18.366, 6.97, -0.95, -0.17, +1.42, +0.92, 1.17; 19.457,
7.09, -0.86, -0.18, +1.46, +0.95, 1.60. Standard deviations are generally
< 0.01 mag, except in U-B, where it is generally 0.05 mag.
