                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
Tom used NM02 time after Doug finished tonight as he had NM05 2nd half tonight.
Bad magna-sensor error at around 11:15. 60 ad 45 deg crossings.  slew up and down in altitude
corrected the errors.
Clouds appeared around 03:00 and gradually thickened.  They closed us around 05:30 when we could
no longer see v=10 stars in the guider.
