The following plots show Event Detection and Correction hardware errors for RAD 750 and SWIC cards on SECCHI-A and SECCHI-B. As of 2011/01/01, there have been no reported un-corrected errors.
Other HK
The following plots are for Task-Manager module telemetry that exceeded a limit more than a few times in the last year. A yellow horizontal line indicates the Yellow Limit that was in effect, a red line indicates the Red Limit:

SPWX Event Messages
Date: January 24, 2006 4:28:28 PM EST To: secchi_manage NRL Subject: SECCHI HK Event Messages in beacon Folks, This email describes what severity of event messages means and which event messages are currently sent down SPWX. The full list of event messages may be found at http://ares.nrl.navy.mil/public_html/tcvol2/mnemonics/HKEVENTCODE.html. This is in preparation for a meeting sometime before Thermal Cycling to discuss what action to take for each event. Don will be making the meeting arrangements.

2024 Geomagnetic Storms
In May 2024, Earth experienced some of the most intense geomagnetic storms seen in recent years. Solar eruptions that led to these storms were imaged by the SECCHI HI-2 camera on NASA STEREO-A. This image sequence shows the large CME front passing over Earth (far left, not to scale) along with concurrent Kp observations, which shows the Earth's geomagnetic response to the event.
Observations from the SECCHI HI-2 camera on May 12, 2024 (top), along with the concurrent "kp" geomagnetic activity index (lower). The location of Earth is as indicated on the left of the animation. [Credits: NASA/NRL/STEREO]
