SDO Day 42: HMI Opens Door

At 11:00 am EST this morning HMI began opening their door. This door protected the front window and optics from damage but can now be opened to let the Sun shine in. Sunlight was used to illuminate the front window and study the optical performance of the telescope. A sunspot could be seen in these engineering images.

Noon: Here are the HMI team members who did the commanding in the MOC, congratulations HMI!
