Be star V442 and
During the OHP spectro party, I observed V442 and on 27th and 30th of July. The latest spectrum in BeSS was in absorption and now the h-alpha line is in emission with increase between the 2 last observations. Weather is not permitting to follow tonight... we are probably capturing the emission event.
This star is well known for having transitionned to emission several times in the past. Valerie

Re: Be star V442 and
Hello Valerie, I report some observations that show H-alpha line strength increasing. All spectra are submitted to BeSS.
