                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 High winds, dust, clouds, and a few raindrops kept us closed for most
 of first half.  After midnight, the dust finally dropped below the
 limit and we were able to open.  Unsurprisingly, the focus was quite
 far off when we began observing with a warm telescope, and it changed
 considerably over the course of the morning.  Seeing ranged from
 moderate to poor.
 The TUI was in use again tonight due to the unresolved firewall
 issues.  Everything worked well, but the user reported that his
 dither scripts, using boresight offsets, were not actually moving in
 X and Y on the chip.  This may indicate a need to update the spicam
 instrument block.
