Yep, I found the same Ken. In general, within the resolution available to me, from 3-6 Dec the Ha & Hb emissions flattened gradually while the adjacent absorption lines deepened, peaking 6 Dec with a flat Hb and a fairly flat, slightly broader Ha line. On the 7th the P Cygni profile is gone and the hydrogen emission lines are re-asserting themselves. Will be interesting to keep following it on a night-to-night basis.
