                ------------- ACTIVITY LOG --------------
Observing Specialists: G.Saurage
Thin cirrus increased first half as did dust levels. Although we had
surprisingly good seeing for these conditions. We continued to observe
until 01:40 when the clouds were too thick and the dust levels outside
were getting uncomfortably high. Could not open again.
No telescope problems.
