               ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Az Velocity Scale was 583.0, measured 583.7, 588.1; 585.9. No Change.
 Nice night with decent seeing.
 Mike was quite happy with the performance of the telescope and instrument
 first half. He seemed quite excited by the data they collected on a tour
 of the outter solar system (Pluto, Neptune, Uranus and moons) tonight.
 APOLLO had a record breaking night. Russet reported they collected 65K
 returns. This is close to the yield for the McDonald station and perhaps
 half or a third of the entire yield of the French station EVER collected.
 They made four rounds through the Apollo reflectors in an hour.
 Second half went smoothly as well. Sarah felt she was able to get lots
 of useful data.
 No problems with telescope or instrument.
