SUPERNOVA 1995al IN NGC 3021
     S. Pesci and P. Mazza, Milan, Italy, report their visual
discovery of an apparent supernova some 25" west-southwest of the
center of NGC 3021.  On Nov. 1.04 UT, they estimated mv = 13.0-13.5,
noting that no star appears at this position on the corresponding
image in the Carnegie Atlas of Galaxies or on the Palomar Sky
Survey.  Pesci reports that nothing unusual was noted during an
observation of this galaxy on Oct. 25.2, with an estimated stellar
limiting visual mag of 16.0-16.2 outside of the galaxy (but perhaps
closer to 15.0 in regions that are superimposed on the galaxy
itself, as in this case).  G. M. Hurst, Basingstoke, England,
estimates mag 13.2 for SN 1995al from an unfiltered CCD image
obtained by M. Armstrong (Rolvenden, U.K.) on Nov. 2.1.
     C. Pollas, Observatoire de la Cote d'Azur (OCA), reports that
a 10-min exposure with the OCA Schmidt telescope on Nov. 2.19 UT
shows a star of mag V about 14.3 that is not present on the
original Palomar Sky Survey.  SN 1995al is located at R.A. =
9h50m55s.97, Decl. = +33o33'09".4 (equinox 2000.0), which is 15".0
west and 2".9 south of the center of NGC 3021.  A nearby star (V
about 16.0) has position end figures 58s.57, 27".40.


NOVA AQUILAE 1995
     A. W. Neely, Silver City, NM, reports that the nova's
lightcurve in V, R, and I continues a smooth, exponential decline,
while showing a significant blueward shift.  From Mar. 29 to Oct. 2,
V-I dropped from +1.9 to +0.07.  Magnitudes from Oct. 2:  Johnson V
= 13.12 +/- 0.05; Cousins R = 12.92 +/- 0.05; Cousins I = 13.05 +/-
0.05.


COMET 122P/DE VICO
     Total visual magnitude estimates (cf. IAUC 6239):  Oct. 1.13
UT, 5.4 (R. Haver, Frasso Sabino, Italy, 15x80 binoculars); 3.49,
5.2 (A. Hale, Cloudcroft, NM, naked eye); 5.48, 5.1 (R. Keen, Mt.
Thorodin, CO, naked eye); 9.19, 5.3 (M. V. Zanotta, Laino, Italy,
20x80 binoculars); 15.11, 5.4 (L. Kiss, Szeged, Hungary, 20x60
binoculars); 19.23, 6.2 (A. Pereira, Cabo da Roca, Portugal, 9x34
binoculars); 22.17, 6.3 (A. Diepvens, Balen, Belgium, 8x50
binoculars); 28.74, 6.3 (H. Luethen, Amrum, Germany, 10x50
binoculars); Nov. 2.09, 6.9 (C. E. Spratt, Victoria, BC, 0.10-m
refractor).
