              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
During checkout I found the DIS slitwheel rotated slightly (maybe 20 deg slit rotation), this may have occured while I mounted the instrument, although I didn't handle it rough.  Rotating the slit to another position didn't re-algn but Re-homing the slitmask seemed to fix the problem.
No problems tonight except as noted above, it did not give me any problems after I homed the wheel tonight.
