Beginning on 28 December 2021, a problem with the Hinode attitude control system has stopped all Hinode science operations. EIS observations resumed on 1 March 2022, but uncertainties remain over whether Hinode can maintain a stable roll angle. The effects of this on EIS data are being assessed.
Beginning on 28 December 2021, a problem with the Hinode attitude control system stopped all Hinode science operations. EIS observations resumed on 22 February 2022, but there were anomalous roll angles (one dataset on 23 February was rolled by 90 degrees) for about two weeks. The roll angles stabilized after this to variations of 1-2 degrees. Since the incident, the roll angles determined from XRT images are monitored at [https://solar.physics.montana.edu/HINODE/XRT/roll_angle/|https://solar.physics.montana.edu/HINODE/XRT/roll_angle/].
