                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 We were open all of first half waiting for sucker holes that never came.
 Finally at 1am dust levels spiked and we were forced to close. Levels
 never dropped low enough to reopen. I spent the night working on the
 apoguide webpage and helping George from GSFC check out the GFP.
