I took a spectra this morning about 2:30 so at an airmass of 1.9
With a quick check at the time, the Ha is much stronger and there seems to be a widening of all of the lines especially towards the blue. I will have to check my calibration but the telluric lines were identical with my last spectra so it should be real.
I will process it properly tonight when I'm home from work.
