DR information

OP main: 2026/05/19 11:06:00 - 2026/05/26 10:59:00 (UT)

Remaining amount
(prediction)

4479 Mbits @ OP_START ( 2026/05/19 11:06:00 )


DR usage: The DR would become empty on May 20 at 16 UT if all telescopes took no images until that time.

daily note

Co-alignment program run:
Please run co-alignment program during the period for the three instruments.
- If the solar condition is not permitted, please delay to the next timeline.
- The sequence should start exactly 15 minutes after the pointing change to stabilize the satellite pointing drift.
- 2 hours for N-limb at *** 930*** arcsec and 2 hours for E limb at *** -970*** arcsec.
- Not necessary to be during SAA-free time.
- For XRT, take G-band data every 5 minutes instead of 8 minutes. This is just for the N limb run. 8 minutes cadence is still OK for the E limb run.
- For XRT, please take data even during SAA and twilight periods.
- For SOT, please use CTM HYSTERISIS (not CT RUN) at the start of each SP program
- For EIS, please run Imada's new co-alignment program
