Camera Anomaly Reaction Plan

The following is the reaction plan for a camera anomaly on either AIA or HMI.

Anomaly Description

The anomaly is identified by having the DATAMIN value for a single camera lock up at zero; an occasional zero is of no concern. The recognition of the anomaly having occurred is the responsibility of the JSOC team.

Refer to the Combined AIA/HMI Recovery Procedure for instructions on how to recover from a DATA MIN camera anomaly.

Reaction Plan for AIA

If there is a Major Flare Watch in progress:

• React the same as for the HMI Doppler camera chain.

If there is NOT a Major Flare Watch in progress:

• If discovered at night, fix the problem the next day, even if the next day is a weekend or holiday.
• E-mail both the local team and the FOT in order to make the next day's recovery begin as early as is practical.
• The time without normal images on one AIA telescope would typically be around 20 hours.

AIA Recovery Procedure

Here is the Recovery Procedure that should be used to recover from the next AIA anomaly of this sort.

Reaction Plan for HMI

If the anomaly occurs to the HMI Doppler camera (i.e., CAM = 2) chain:

• Contact NASA and our own personnel immediately after discovering it and have people go into the JSOC and MOC as soon as possible (by formal agreement, within 2 hours of notification).
• For occurrences not during regular working hours this would typically result in the loss of good images for around 10 hours (6 for recognition and 4 for coming into the JSOC and MOC and fixing the problem).

If the anomaly occurs to the HMI Magnetic camera (i.e., CAM = 1) chain:

• If discovered at night, fix the problem the next day, even if the next day is a weekend or holiday.
• The time without normal images on the HMI Magnetogram camera would typically be around 20 hours.
