Hi Jack,

I am not monitoring H alpha as the coverage there already looks pretty good.

I am just covering ~3800-4100 A (which covers H epsilon – H10  including Ca H,K )  This is the same region I monitored during the 2012-2013 eclipse of AZ Cas (A similar but much fainter system.)


The changes are very pronounced and potentially scientifically interesting in this region but I was the only one monitoring AZ Cas there. For VV Cep there are a couple of others working in that region though so hopefully we should get good coverage there for this eclipse.
