Yesterdays shot, 7 x 10 minute (just above the trees, observeability will end soon, blue got very hard):
interesting to see the FeII absorption feature pattern matching right the 2 months ago state (that was not so hard to spot: feature got very deep again).
Otherwise the patterns look to be changing considerably only by 0.5-1 day, so far couldn't find other shorter term variation above noise than Balmer lines emission.

Here is a comparison of 3 high resolution H-alpha spectra covering about a month in time. I've labelled what appear to be some subtle changes in the profile. As the spectra are not flux calibrated I'm not sure how much confidence to give to the slight increase in H-alpha intensity and width. This has been a fascinating star to observe, though this may now be my last spectrum until it becomes more favourable again.
