               ------------- ACTIVITY LOG --------------
 Observing Specialists: J. Davenport
 Clouds and lightening during the afternoon. We finally opened after some
rain at 22:12. Occasional small clouds the rest of the night.
 Talked briefly with Larry Carey about the Tertiary problems. He advised I
look for any pointing problems, which may due to problems with the
flexures. No major pointing problems were observed, all targets we slewed
too were within an arc-min of the DISslit center. Generally I saw them
offset in the Altitude direction.
No problems otherwise.
