SOHO Daily Meeting Minutes for Friday 11 July 2003


ANNOUNCEMENTS
-------------
* FOT have resumed regular Y axis antenna movements (nominal HGA control,
  Y axis only, at 00 UT, 08 UT, and 16 UT every day) but the movements
  will be done in high-speed mode (100 Hz) instead of the low-speed mode
  (0.1 Hz) used earlier. This is just in case a thermal cycling problem was
  responsible for the Z axis problems. Thermal cycling is negligible for
  the high-speed mode, not for the low-speed mode.

  Since a concern regarding spacecraft jitter was among the original reasons
  for using the low-speed mode, we would like all instruments to check for
  any noticeable (or rather: significant) impacts due to the very short (less
  than a second) movements at the above times.

* NOTE: We would like to have a common policy for SOHO fits files 
  for the 180-degree rotated periods (they may cover 50% of the 
  remaining mission lifetime). We ask that you DO NOT ROTATE the data 
  in fits files - the rotation should be handled through standard
  fits keywords. 
 
  CHANGED since yesterday - In summary: Make sure your fits file keywords 
  for solar coordinates show actual solar coordinates, *not* spacecraft 
  coordinates! (In addition to specifying the rotation to be applied
  to the image). Check out the SSWIDL routine get_soho_roll for one way of 
  getting the correct input for the spacecraft nominal roll position for 
  an arbitrary time.

* Current RHESSI default target is AR10401. When selecting this 
  target to maximize coordination w/others, use campaign number 6850.

* A basewide network service outage for the gsfc.nasa.gov domain has been
  scheduled for the weekend commencing July 11th at 6:00 pm and ending at 
  12:00 midnight on Sunday July 13th.

* Mounting trace-arch00 will be different than before starting at
  noon on Monday - see Amy if you need more details.
