                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 A fairly peaceful night, alternating clear skies and thin clouds.
 Seeing was mostly poor, especially at the beginning of the night,
 but occasionally improved.
 APOLLO had a little trouble with a bad prediction but managed to
 recover and get usable data anyway.  SPIcam and DIS worked well.  I
 did have to make a moderate correction to tertiary tilts to fix
 pointing, but after that it was very consistent.
