H. Yamaoka, Kyushu University, writes that low-resolution spectroscopy obtained by M. Fujii (Ibara, Okayama, Japan) on Feb. 12.88 and 14.83 UT, and by H. Naito (Nishi-Harima Astronomical Observatory) on Feb. 14.86, shows a much bluer continuum than in the spectroscopy taken on Feb. 5.87 (cf. IAUC 8803); the new spectra resemble the spectrum of an F-type star. Balmer lines (relatively weaker than in the Feb. 5 spectrum) show clear P-Cyg profiles (expansion velocity about 500 km/s), along with other weak lines.
