checking IP Per before the season closes

I just noticed the reduction in H alpha emission in Be star IP Per reported by Umberto has not yet been confirmed

so I thought I would check it tonight using the LHIRES 1200 before it is too late in the year. It looks like it is still in net emission but perhaps not as strong as in 2012 (a single 600sec exposure so far)
