[vsnet-alert 13285] T Pyx spectra (Apr. 24, 29 and May 5)

[K. Imamura]

   We have performed further spectroscopic observations (R~400) of T Pyx 
at the Tanabe Personal Observatory in Okayama-city. On April 24, we can 
find Fe II lines on the spectrum. These lines are strengthend day by day, 
and also the P Cygni profiles seem to become prominent. On May 5, 
H-alpha shows clear P Cygni profile. An absorption minimum of the H-alpha 
from the emission peak shows approximately 1400 km/s expansion velocity.

Our spectra can be seen in the following:
