The SASHe collector was experiencing shading from the nearby AOS mast during the early morning. The time when the shadow falls across the SASHe varies somewhat but it occurs roughly in the 3 hour interval from 13:00-16:00 UT. It shows up as a direct normal irradiance dropping to zero or near zero. It is possible to distinguish this from actual cloud cover by examination of the MFRSR direct irradiance.

Suggestions:	Do not use SASHe irradiance measurements during impacted periods.
