-- Review of last week's XRT observation (7-14 July, 2012) --

• Solar activity was very high this early July, with 2 X-class flares from AR11515 and AR11520.
  Major Flare Watch called many days from the Max Milleneum Chief Observer.

   4-Jul : Major Flare Watch.
   5-Jul : GREAT Flare Watch.
   6-Jul : Major Flare Watch.
   7-Jul : Major Flare Watch.
   8-Jul : Major Flare Watch.
  10-Jul : Major Flare Watch.
  11-Jul : Major Flare Watch.
  12-Jul : Major Flare Watch.
  13-Jul : Major Flare Watch.
  14-Jul : Major Flare Watch.
  

AR11520 has been a main target this week (7-14 July).

• Synoptic observation (Whole Sun images).
  Movie(7-jul to 15-jul).

• Support of Hi-C sounding rocket mission.
  High-resolution Coronal Imager(Hi-C), on a sounding rocket (36.272) was successfully launched on 11-Jul, from White Sands Missile Range. Hi-C will collect 150-kilometer-resolution images of the sun in the EUV spectrum. 5 times greater resolution than any previous imager.
  The launch window was set to 18:55UT (12:55MDT). XRT ran a special program to support this mission (18:53-20:00UT).

  Program(XOB#1901): HI-C - Ti/Poly(256ms/1024ms), AEC3/2 -512x512- 30sec cad
  

  Composite movies during the support.

• X-flare observation (X1.4 flare on 12-Jul, 15:37-)
  Data coverage.
  Movie.    just comparison : Movie before coalignment by ALIGN_CUBE_CORREL.
  Sigmoid. Similar to
  the Bastille Day Flare (14-Jul-2001).
