Here is a low resolution spectrum for the night 3/4 June. The continuum continues to cool and now matches a black body temperature of 9000K or an F0v star ((B-V) = 0.29.) The features are still weak with a very broad H alpha component with some structure evident at higher resolution. The higher Balmer lines are increasing in absorption blue shifted by ~8000 km/s
