| Sumario: | G. L. Bosch, R. H. Barba, and N. I. Morrell, Observatorio Astronomico, Universidad Nacional de La Plata, report that echelle spectroscopy (range 460-780 nm, resolution 0.04 nm) obtained of the nova at CASLEO Observatory on Oct. 26.149 UT shows strong, low-excitation emission lines of H, Fe II, [O I], O I, Na I, and possibly [Ni I] with broad P-Cyg profiles. Terminal wind velocities measured from the absorption-profile edge in H-beta indicates expansion of up to 1800 km/s, while Fe II and Na I lines show a slower expansion velocity of 950 km/s. The FWHM of the H-alpha emission was about 1400 km/s. |
