                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
07:43:45 got a BadAltStatus and error too large in the TUI status window.  This stopped the
altitude tracking.  Axis stop/init fixed the problem quickly.  No significant time was lost.
Floor space heater plugged in for vacuum pump this morning.
