Chandra Announcement: Temporary Restrictions on DDT/ToO Triggers

[Tara Gokas]

Temporary Restrictions on Chandra DDT and ToO triggers: 25 July - 9 August 2020

Due to a major flight operations update and the ensuing gyro calibration which will allow Chandra to return to the use of a single IRU (i.e. gyro pair) and potentially improve the thermal conditions on the spacecraft, we are limiting ToO and DDT triggers as follows:

25 July - 9 August 2020: No ToO or DDT triggers which require observations to be scheduled during this time period will be accepted

30 July - 1 August 2020: No ToO and DDT triggers of any kind will be accepted
