Yes I did
Data from last night
V= 4.937
B = 5.028
This is a slight drom in V and less of a drop in B since my last measurement on 5/1/14
The spectra shows an identical relative Ha emission but an increas in the blue continuum.
When I graph the flux calibrated data, there has been a drop in the absolute height of Ha but an increas in the blue continuum. This fits with the reduction of B-V my photometry displays.
