SOTSP: Active Region Evolution
2007-05-02T23:20:00 to 2007-05-03T03:00:00
Science Goal: Active region tracking; AR; AR10940
Program: Fast map 164 arcsec
Target: AR10940
xcen=204 ycen=-100
Instrument: SOTSP
HOP/JOP: 0
Description:
AOCU_N\D_AUTO will be issued to return to N/D AUTO judgement mode. After this execution, we will see the periodic transitions between gyro-only control (for night period) and gyro-sunsensor control (for day period), because of margin in AOCS onboard N/D calculation. Note that pointing jump may occur at the transition from gyro-only control to gyro-sunsesor control. At the worst case, the magnitude of jumps may be 40 arcsec. andnbsp
