SUPERNOVA 1986M IN NGC 7499
E. Cappellaro and L. Rosino, Asiago Astrophysical Observatory,
report the discovery by Candeo of a supernova 33" north and 15"
east of the center of NGC 7499 (R.A. = 23h07.8, Decl. = +7 19', equinox
1950.0); on Dec. 7, the object was at mpg = 16.5.
NOVA ANDROMEDAE 1986
The following precise position has been reported, obtained at
Tokyo Astronomical Observatory's Dodaira Station on Dec. 8.6 UT by
M. Kondo with the 0.50-m Schmidt telescope and measured by H.
Kosai: R.A. = 23h09m47.72, Decl. = +47 12'00.8 (equinox 1950.0).
K. Krisciunas, Keaau, HI, reports the following photoelectric
measurements: Dec. 9.340, V = 6.83, B-V = +0.41. Visual magnitude
estimates: Dec. 8.94, 6.3 (P. Schmeer, Bischmisheim, W. Germany);
9.31, 6.8 (D. Pickup, Hilo, HI); 9.82, 6.9 (G. Hurst, Basingstoke,
England); 9.85, 6.8 (M. Taylor, Wakefield, England).

F. Strafella, Physics Department, University of Lecce; D.
Lorenzetti and L. Spinoglio, Istituto Fisica Spazio Interplanetario,
Consiglio Nazionale Ricerche (CNR); and P. Persi, Istituto de
Astrofisica Spaziale, CNR, report: "The following infrared
magnitudes have been observed at the Tirgo telescope: Nov. 15.10 UT,
J = 10.9, H = 10.4, K = 10.0, L = 8.3; 27.95, 8.4, 8.3, 8.2, 8.3;
28.83, 8.6, 8.4, 8.4, 8.1; 28.88, 8.4, 8.3, 8.3, 8.5; Dec. 5.00,
9.6, 9.4, 9.3, -. Errors in J, H, K are < 0.05 mag, and in L are about
0.2 mag. Thus, delta J was about -2.5 mag from quiescent state to outburst
state. Since delta V during the same time interval was about -2 mag, it
seems that at maximum brightness the star's outer disk radius is
larger than at quiescence."
Visual magnitude estimate by J. E. Bortle, Stormville, NY:
Dec. 5.08 UT, 11.3.
