                  ------------- ACTIVITY LOG --------------
 Observing Specialist: N.C.Hastings
 I opened the dome at 19:45 to begin cooling after CU finished cals. The
 sky was clear with some cirrus, temps warm. Seeing was decent and no
 problems were encountered with startup.
 Telescope ran smoothly all night. Seeing became very bad in second half
 and variable with continued cirrus. No other problems encountered though.
