                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 We had mostly clear skies at sunset however I was nervous about radar
 returns to our west and north east so I delayed opening. Within an
 hour we had lightning within 11 km of the site and clouds began to
 form over head. Soon the skies became opaque. We had a few light rain
 showers during the night. At 03:15 the second half observer gave in
 for the night. I was doing morning instrument fills at 04:30 when I
 took a peak out the dome at the skies. The situation looked ok to open
 and radar returns had dissipated by now. I quickly switched to the
 echelle, opened and took some exposures for NM07 through variable
 cloud cover until sunrise.
