Estimated Total Execution Time (hours, including overheads)

• 2h

General Description

• The aim is to get a time series of the (supposed) magnetic field in HR7355
   over the rotational phase. The period is probably 0.52days (inferred from photometry),
   but could also be different. The actual period will be verified/determined spectroscopically
   with FEROS observations on Jul 13 and Sep 5.

• No Waiver Request was submitted

Critical Observing Condition Constraints

• We gave no constraints on observing conditions, and in fact the program
   is on a bright star and can be executed under basically all conditions. However:
  
  1) The integration time has been calculated for a seeing of 1.1 arcsecs or worse.
   If the seeing is better, the exp_time must be REDUCED in order to avoid saturation.
  
  2) If the conditions are outside the operational limit (THK or seeing worse than
   2") this program can still be executed, but we request an adjustment of exposure
   time to obtain counts not less than about 50% of the linearity limit, i.e. 15000ADU
   or more.

Time-Critical Aspects

• There are no strict timing instructions, except that the OBs must not
   be executed one after the other in a straight sequence. Always observe something
   else between two OBs.  Since subrun A was not approved (FEROS observations in April)
   we ask to execute these observations not before July, to ensure that we will be
   able to coherence the data with the spectroscopy. If possible, execute the series
   actually in July, when the star is up all night, over about one week at different
   times in the night. If this does not work, still once the first OB was executed,
   it would be best to execute the remaining OBs soon.
