April

Although EOVSA observed many interesting events in April, the cooled receiver on the 27-m antenna, essential for phase calibration, was not working from about April 1 - May 7, 2022. The cause of the long outage was that the manlift needed to repair the receiver had a flat tire that required a long leadtime to replace. Any events seen during this period are available in total power only--no imaging is possible.

Note: For much of August the array was down due to a planned power outage to install some new power equipment. The event on 2022 Aug. 30 was observed while the array was not yet tuned for delays.

While STIX detected a flare occurring simultaneously, it was located near the east limb and not the X1.1 flare in the western hemisphere. The Solar Orbiter couldn't observe the X1.1 flare due to its positioning.
