				AAVSO ALERT NOTICE 200 (February 15,1995)

0935+O5 SUPERNOVA 1995D IN NGC 2962

We have been informed by S. Nakano, Sumoto, Japan, of the discovery of a supernova by 
Reiki Kushida, Yatsugatake South Base Observatory, on Feb. 10.756 UT at magnitude 14.0 
(unfiltered CCD, 0.25-m f/6.3 Schmidt- Cassegram telescope). No corresponding image 
appeared to magnitude 17 on frames taken by Kushida on Dec. 3, 1994, Jan. 13, 1995, and 
Jan. 25, 1995. Also, no corresponding image appeared to magnitude 14.8 on T-Max films 
taken by Y. Kushida on Jan. 31 (IAU Circular 6134).

A precise 2000 position was measured by Y. Kushida:

		R.A. = 09h 40m 54.79s 	Decl. = +05deg 08' 26.6" (2000),
precessed to:

		R.A. = 09h 38m 17s	Decl. = +O5deg 22'05" (1950).

The supernova has been confirmed spectroscopically by S. Benetti, C. Mendes de Oliviera, 
and A Manchado, European Southern Observatory, on Feb 13.18 UT. They report that it 
is a type Ia supernova, one week before maximum light (IAU Circular 6135).

Observations of this supernova include: Feb 11.475 UT, 13.9 CCD (unfiltered) (Y. 
Kushida, Yatsugatake, South Base Observatory, Japan); 11.49, 13.95 CCDV (K. Sadakane, 
Osaka Kyoiku University); 11.53, 13.91 CCDV (Sadakane); 11.68, 13.86 CCDV 
(Sadakane); 11.549, 13.71 CCDV (D. Nogami, Ouda Station, Kyoto University); 11.560, 
13.7 visual (S. Takahashi, Dynic Astronomical Observatory, Shiga, Japan, via T. Kato); 
12.313, 13.87 CCDV (R. Mutel, University of Iowa, based on 12.0 GSC star); 12.590, 13.53 
CCDV (Nogami); 13.604, 13.63 CCDV (T. Yokoo, J. Arimoto, K. Tanabe, Osaka Kyoiku 
University, based on 13.9 GSC star on accompanying chart).

Please use the accompanying AAVSO 'e' scale chart prepared by C. Scovil to observe this 
supernova and report your observations to AAVSO Headquarters by telephone, fax, or 
email so we may inform the astronomical community. Please be sure to indicate which 
comparison stars you used.

Congratulations to Reiki Kushida on her latest discovery!

1900-01 NOVA AQL 95

This nova (see AAVSO Alert Notice 199) has been confirmed spectroscopically by R. M. 
Wagner and R. Bertram, Ohio State University, and S. G. Starrfield, Arizona State 
University, who detected strong H beta and permitted Fe II emission lines in their optical 
spectra obtained on Feb 10.54 UT with the Perkins 1.8-m telescope. "The spectra confirm 
this object as a slow 'Fe II' -class nova in its post-maximum phase of development." (IAU 
Circular 6134)

N Aq195 has also been confirmed spectroscopically by O. Ohshima, M. Shimizu, and K.
Ayani, Bisei Astronomical Observatory, and M. Suzuki, Kanazawa Institute of Technology, 
on Feb 10.9 UT, and by T. Harrison, New Mexico State University, on Feb 10 UT.

Recent observations of N Aq195 include: Feb 10.18 UT, 8.8 L. Kiss, Szeged, Hungary ; 
10.198, 8.9 (L. Szentasko, Veresegyhaz, Hungary); 10.551, 8.6 (P. Collins, Scottsdale, AZ); 
11.447, 8.5 (C. Stephan, Sebring, FL); 12.436, 9.0 (J. Bortle, Stormville, NY); 13.119, 8.9 (D. 
Overbeek, Edenvale, S. Africa); 13.445, 9.4 (Bortle); 14.18, 9.0 (L. Kiss, Szeged, Hungary).

Accompanying are AAVSO 'b' and 'd' scale charts for N Aql 95 prepared by C. Scovil. 
Please use them to observe this nova, and indicate which comparison stars you used in 
making your estimates.

1436-63 NOVA CIR 95

Please continue to observe this bright southern nova using the chart distributed with 
AAYSO Alert Notice 198 and report your observations to AAVSO Headquarters.

Recent observations of N Cir 95 include: Feb 5.617 UT, 8.44 V (A.C. Gilmore, Mt. John 
University Observatory, New Zealand); 9.513, 8.73 V (P.M. Kilmartin, Mt. John University 
Observatory); 9.954, 8.9 (L.A.G. Monard, Pretoria, S. Africa); 10.041, 8.9 (Monard); 
11.882, 8.9 (Monard); 12.5, 8.9.(T. Cragg, Coonabarabran, NSW, Australia); 12.614, 8.74 V 
(Gilmore);12.846, 9.0 (Monard); 13.122, 9.2 (D. Overbeek, Edenvale, S.Africa).

REMINDERS

Please remember the following requests for your assistance. Lists of target stars may be 
found in the corresponding AAVSO Alert Notices:

AAVSO Alert Notice 196: Hipparcos red variables for photometric calibration (through 
February);
