WEATHER COMMENT: Tue May 25 16:14:45 GMT 1999
Cool, clear, brisk southeast wind.

**PSPT PROBLEM**: Tue May 25 17:52:05 GMT 1999
After removing several covers, I found the focus stepper.  I cannot see
the rest of the mechaanism without disassembling the secondary optics 
package, I think, NO DOCUMENTATION ON MECHANICAL ASSEMBLIES!!!!, three versions
of optical schematics are just ray tracing with the lenses and filters
drawn in, versions are different so apparently two are obsolete,  also
figured out how to move the focus with the PC, NO DOCUMENTATION ON THIS
EITHER!!!! to test the focus motor and mechanisms.

Before I started to open things up, I tried a Run to listen to the focus
mechanism, BUT, guider would not lock on for some reason.

I will have to query Roy before proceeding with focus mechanism check-out
to avoid removing something that will screw up alignment.

Found out why guider would not acquire sun.  Beam splitter is not secure
in its mount.  I noticed that the beam to the quad cells was not 
projecting on the lens when the spar was closely pointed toward the sun.
I was able to yaw beam splitter about the stem and move the beam onto
the quad cell lens.  Once this occurred, the guider locked on and the
Run program continued.  If it is possible to tighten the stem down, I
will do that during the wait between data runs.

**PSPT PROBLEM**: Tue May 25 19:02:39 GMT 1999
Initial (around 1900 UT) data in focus.
Tue May 25 19:08:48 GMT 1999    MKIII    Start Cal
**PSPT PROBLEM**: Tue May 25 19:19:51 GMT 1999
I did see one image of Ca out of focus during cal series where xy
motion is going on.  I did not see image before the out-of focus one,
and next image, Ca again offset in xy, was in focus.  Shift to red
after the Ca xy offset series was in focus.

Stopping to reconfigure dome shutter.

**PSPT PROBLEM**: Tue May 25 20:02:40 GMT 1999
Could not eliminate the yaw in the beamsplitter no matter how tight
I made the screw, I did not want to tighten it too much for fear of
stripping the screw or the threaded hole.  Position holds so long as
no one deliberately or accidentally moves it.  Repositioned the 
beamsplitter to correct alignment after tightening both axes.
**PSPT PROBLEM**: Tue May 25 20:58:07 GMT 1999
Opened up main optics housing cover (plate with the latches) and accessed
the stepper motor for the focus mechanism.  According to Roy, only the 
lead screw extending out of the motor can be lubricated, the rest of the 
mechanism is sealed.  Phew! this avoids having to remove the entire
secondary optics pacckage!  Extended screw with "fcs goto blue" command on PC.
Lubricated screw threads with Dow 33 silicone grease.  Exercised the 
focus to spread the grease to the threads.  Squeaky noise was eliminated.

2100 UT data run was good, focus was good.
