* Did not open up tonight because of the weather. SAMS tests all night.
* ELS does not show alarm/warning for rain, but the EDS does show the
correct status.

Notes and messages
----------------------------
* The last temp control unit for the aircon, which we installed last
night in the control room, is now dead. And it's freezing in here!!!! :(
* ELS issues:
During the day we had dew point warning on SOMMI which was clearly wrong.
Text messages are being sent by the ELS to the standby phone
which are irrelevant (SAMS comms lost, DEW point warnings
etc). This needs to be fixed before the standby person drowns the phone...
Night temp variance was yellow both nights, but the temps were
nicely equalized and temp gradients are flat as a pancake.
* Aircon for conditioning the building during the day does not work
due to low levels of glycol. Opening louvers early instead.
* Video feed from star tracker is working!! Thanks Charl and Hitesh!
Erm.. you do know I don't have a kingdom to swap for the camera,
right? ;)
* Tracker brakes release error three times. Twice it recovered
by itself, the other time it did not and did not move, although reporting
green and SLEW.

========================================================
----------------------------
Notes and messages
----------------------------
* SPAIN ARE WORLD CHAMPIONS!!! FOR THE NEXT FOUR YEARS!!!! Hip hip hurrah! :)
* Both Temperature control modules for aircon in the control room and
the computer room are broken. We "stole" the newly arrived one
intended for the computer room and installed in the control room.
* External dewpoint alarm triggered when T-ext=10?
* With nearly every point to target, we get an error on a fine igloo
alarm. Allegedly it's a dodgy sensor so we dutifully ignored it (it's
hardly going to affect our IQ anyway!).
* Again, approaching CCAS clockwise the structure sometimes doesn't
quite make the correct az (59.986 instead of 60.04) so no spots for
mirror alignment. An X instrument shift of -300 brings spots into
view.
* Structure CCW limit 1 reached but structure does NOT go onto fault
and reamains ready. It won't move though, so it should be a fault.
* Had a 'too many loops' followed by 'not enough rects' error so had
to restart CCAS.
* Had one fatal following error on tracker that aborted our track. OK on repoint. Charl, temp on the rho motor was OK.

Summary Night Report 20100708
Report for night 2010-07-08
SA: Alexei
SO: Fred
Others: Siphelo, Zolisa
========================================================
Summary:
1. We continue our checks of alignment and its degradation.
Segment 65 is out of the loop.
We worked only with Side1 tonight just to see how the method works.
Side1+Side2 alignment degradation have to be checked during next weeks.
I loged rms of Side1 altogether with temperature and humidity at 2m.
Unfortunately, because structure errors all the time, we were
need to put structure down and start it again. So, our results
of the degradation are take it into account somehow.
2. Teaching of new SOs was continued during the day and the night.

Summary:
1. SPS error was generally fixed by Hitesh and Deon during day time.
Segments 3 and 41 were disconnected.
2. Two new SOs arrived today and Fred started teaching.
3. The alignment is working in general, but we need good conditions
to make it properly.
