p Cyg EW decrease (?)
Posted: Sat Jan 05, 2013 9:52 pm
In my today observation of p Cyg I noted a decrease in H alpha intensity and EW .
EW December 12, 2012 = -87.2529 A (max intensity = 20.99)
EW January 05, 2013 = -76.4043 A (max intensity = 18.80
EW measured with ISIS, lambda range 6510 6617.
Probably somebody can confirm a similar behaviour ?
Tx,
Marco
