Doors Closed On SECCHI-B
For Momentum Dump on Behind 2014/07/28 16:15, the COR 1 and COR 2 doors remained closed for 33 hours due to a schedule error. Here are the temperature plots from that event.
Temperature Anomaly On SECCHI-B
Plots of all housekeeping board temperatures at 1 hour resolution from 2007/03/01 - 2015/11/20(A) - 2014/06/13(B)A ~10 deg increase in electronics temperatures is observed on Oct 22, 2012. A similar thing happened on Feb. 24, 2009, and it corrected itself on Apr. 15, 2009. |

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]
