[vsnet-be 135] Re: [vsnet-spectroscopy 36] V1294 Aql



   If I'm not being too presumptuous, Christian was probably referring
to the spectroscopic outburst - his spectra show that the intensity of
H-alpha has nearly doubled in the last two months and has more than 
tripled since 2000.  The central absorption core has disappeared as
well.

   It's a good idea to keep an eye on it since visual changes can
lag behind the H-alpha increase...or not!

   The Hp light curve shows a nice descent from ~6.9 to ~7.2.  It
seems to have stuck at around 7.2-7.3 ever since.  There are Be stars
that  stay nearly the same visual magnitude for years and then
suddenly fade.

   V1294's spectral type is nearly identical to Delta Sco's, by the
way.  A recent paper on Delta Sco shows that the H-alpha "brightness"
(flux relative to the nominal, pre-eruption flux level) has increased
steadily since the outburst began while the visual brightness has
varied quite a lot during the same time.
