SUPERNOVAE 2005he AND SN 2005hg
     M. Modjaz, R. Kirshner, and P. Challis, Harvard-Smithsonian Center for
Astrophysics; and T. Matheson, National Optical Astrononmy Observatory,
report that a spectrogram (range 350-740 nm) of SN 2005he (cf. IAUC 8621),
obtained on Oct. 27.12 UT by Modjaz with the F. L. Whipple Observatory
1.5-m telescope (+ FAST), shows it to be a type-II supernova with strong
H_alpha emission, a H_beta P-Cyg profile, and other elements in absorption.
Adopting a recession velocity of 7490 km/s for the host galaxy, as measured
from H_alpha emission of an H II region in the host galaxy, the expansion
velocity derived from the minimum of the H_beta line is about 8700 km/s.
A spectrogram of 2005hg (cf. IAUC 8623), taken as above on Oct. 27.30,
reveals it to be a type-Ic supernova around maximum; the spectrum is
similar to spectra of SN 1994I (Filippenko et al. 1995, Ap.J. 450, L11)
taken around maximum light.
