                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
AZ velocity scale measured 581.1 was 577.0 changed 579.0
Alt velocity scale measured -635.3 was -637.0 changed +636.0
I rotated the tertiary at the start of the night with no problems.
When rotating to BC1 got the following error.
12:36:12 APO.Jack-Obs1 375 telmech f errtxt=""; UNPARSEDTEXT="?CHKMV one or more axes didn't make
it (SC<> 001). SC, or 0 if not moved:  000,  000,  000,  000,  008\"\""
Lost about 30 mins due to tert not wanting to rotate to BC1.  Nick helped get it going again.
Despite the problems APOLLO was still able to get some returns.
