SUPERNOVA 1995D IN NGC 2962
S. Nakano, Sumoto, Japan, reports the discovery by Reiki
Kushida (Yatsugatake South Base Observatory) of an apparent
supernova of mag 14.0 on an unfiltered CCD frame taken on Feb.
10.756 UT with a 0.25-m f/6.3 Schmidt-Cassegrain telescope. Y.
Kushida has measured the following accurate position from five CCD
images by the discoverer: R.A. = 9h40m54s.79, Decl. = +5o08'26".6
(equinox 2000.0), which corresponds to a point 11" east and 90".5
south of the center of NGC 2962; no image brighter than mag 17
appears at this position on CCD images secured by R. Kushida on
1994 Dec. 3, on 1995 Jan. 13, and on Jan. 25. Comet patrol T-Max
films taken by Y. Kushida on Jan. 31 show no star brighter than mag
14.8. A further unfiltered CCD image by Y. Kushida on Feb. 11.475
shows SN 1995D at mag 13.9 +/- 0.2.
NOVA AQUILAE 1995
R. M. Wagner and R. Bertram, Ohio State University; and S. G.
Starrfield, Arizona State University, report: "Optical spectra
(range 450-570 nm, resolution 1 nm) of the nova candidate described
on IAUC 6133 were obtained at the Perkins 1.8-m telescope on Feb.
10.54 UT. The spectra show strong H-beta and permitted Fe II
emission lines. The continuum over this spectral range is
relatively flat. The FWHM of H-beta emission is about 1200 km/s.
The spectra confirm this object as a slow 'Fe II'-class nova in its
post-maximum phase of development."
O. Ohshima, M. Shimizu, and K. Ayani, Bisei Astronomical
Observatory; and M. Suzuki, Kanazawa Institute of Technology,
communicate: "We obtained spectra of this object with the Bisei
1.01-m reflector (+ CCD spectrograph) on Feb. 10.9 UT. Strong
emission lines of H-alpha, H-beta, Fe II (492.3, 501.8, 516.9 nm),
[N II] (575.4 nm), and Na I (589.0 nm) were identified clearly.
The FWHM of the H-alpha line (corrected by the instrumental FWHM of
1.18 nm) is 2.94 nm, which corresponds to a velocity dispersion of
1340 km/s. The H-alpha profile shows red-wing asymmetry."
Additional visual magnitude estimates: 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).
