2021-05-07: Fast, Rapidly Accelerating CME
A fast, rapidly accelerating CME was recorded in the Mauna Loa K-Cor data from ~18:54 to 20:00 UT. Wide loop with ‘warp’ in the northern leg possibly due to rapid acceleration. Very large deflections. CME speed as it left the K-Cor field-of-view was 1100 km/sec with an acceleration of ~510 m/sec^2. Large deflections in adjacent coronal structures. A slower CME was in progress just north of the fast CME. High likelihood that the CME drove a shock.
