Abstract

Medium resolution spectroscopic observations of SN 1998aq made in April - May, 1998, are presented. We confirm its Type Ia classification based on the prominent Si II λ6355 line and other features similar to SNe Ia. No significant sign of hydrogen Balmer-alpha line was seen in high-resolution spectra taken at 8 days before maximum. Preliminary estimate of red-dening and distance modulus, based on the correlation between the line depth ratio of two Si II features around 6000 A and BV RI light curves of Type Ia SNe (Riess et al., 1998), is presented. Moreover, Hα emission from the core of the Seyfert 2 type host galaxy NGC 3982 has also been detected.
