April 2022

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.
