                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 A productive night. Clear skies until 02:30. I closed at 03:00 because
 of clouds even though there was no threat of precip. I reopened again
 at 05:30. Cloud cover was mostly variable even after 05:30. Seeing was
 moderate to poor all night.
 My observer finished 15 minutes into twilight so I used the last 30
 minutes of twilight to switch to the Echelle and get some useful
 data on Epsilon Aurigae for NM07.
 The building and telescope experienced another collision this morning
 as I was closing up. I cleared the collision but the telescope is
 a degree and a half away from its park position.
 No other problems.
