                ------------- ACTIVITY LOG --------------
Observing Specialists: R.McMillan
A beautiful clear night with good to excellent seeing.  Unfortunately
I lost the focus information, but seeing was 0.8" in y, 0.6" in H.
The focus numbers continue to be unusually negative; the guider focus
numbers were normal.
Checkout was rushed due to some difficulty with a new filter set, but
we got on the sky at sunset and everything went smoothly from there.
Pointing was good with all instruments.  I did see the "broken pipe"
error at one point when I tried to open the BC1 eyelid; a hub
startNubs telmech followed by a telmech status cleared it up.
APOLLO observations netted four reflectors, so a successful run.
