                ------------- ACTIVITY LOG --------------
 Observing Specialist: G.Saurage
Overcast skies and local thunderstorms most of first half. Skies began clearing
around 23:30 overhead. Satellite and radar activity nearby all night.
Many problems tonight mostly revolving around using, moving or setting up Agile. Had
some trouble getting started on Agile with the TUI version released today (1.6b2). I
worked most of it out during first half (with help from Fritz and Russell). I
updated the obs-spec wiki pages. Did not discover pinhole was left in Agile until we
got on sky.
PR 1007: In order to physically access AGILE the telescope must be pointed very
high. If the mirror covers are closed and an E-stop engaged the telescope will come
to rest at about 86 degrees alt. This triggers an error reported in the status
window in TUI:'Hit minimum soft limit." Which is confusing because it seems like a
maximum, but the real issue is that it cannot be cleared by an axis init. And TUI
will not slew down untill that error is cleared. So it has to be moved down by hand
or talk2boxes.
PR 1008: The Agile user tonight was comparing images taken at NA2 in the past with
tonight's images taken at TR2. Tonight's images seemed to be rotated about 45
degrees counterclockwise (E of N) from the previous images of the same field, same
coordinates. Then after a spontaneous rotator servo error we slewed back to the same
field and the rotation was off again but in a completely different way. Later
another servo error put the field back to the 45 degrees off position.
PR 1009: A few different times tonight the observer tried to abort a long sequence
of exposures with Agile using the inst gui in TUI (1.6b2). Doing so left the gui in
limbo. Nothing would happen, it would just sit saying "object time... started"  but
not start. A simple nub restart of agileExpose would clear things up, but perhaps
the Abort button is doing something strange?
