V1281 SCORPII = ANOTHER POSSIBLE NOVA IN SCORPIUS
H. Naito and S. Narusawa, Nishi-Harima Astronomical Observatory
(NHAO); and H. Yamaoka, Kyushu University, report that a low-resolution
spectrogram (range 410-670 nm; resolution 1600 at H_alpha) of the possible
nova reported on IAUC 8810 was obtained on Feb. 21.84 UT with the 2.0-m
NAYUTA telescope (+ MALLS). The spectrum shows a broad H_alpha line with
a P-Cyg profile (the FWHM of the emission component is about 1800 km/s),
along with many other weaker lines, indicating that the star is indeed a
classical nova. A narrow Na I D absorption feature suggests the existence
of considerable interstellar reddening.
N. N. Samus, Institute of Astronomy, Russian Academy of Sciences,
reports that this nova has been given the designation V1281 Sco.
