AX Per H-alpha emission line flux

Forums Spectroscopy A couple of symbiotics from earlier in the week AX Per H-alpha emission line flux

It is also worth keeping an eye on the H-alpha emission line in AX Per which shows strong orbital modulation, as do all the Balmer lines. The following plot shows my flux measurements over the last two orbital cycles. Coverage of the first cycle was patchy. The phase is currently about 0.4 and the flux is now rising. It will be interesting to see if the peak is as high as last cycle.
