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 reddening and distance modulus, based on the correlation between the line depth ratio of two Si II features around 6000Å and BVRI light curves of Type Ia SNe (Riess et al., 1998ApJ...504..935R) is presented. Moreover, Hα emission from the core of the Seyfert 2 type host galaxy NGC 3982 has also been detected.
