CME Observed Time: 2024-05-13T09:12Z
iSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/30814/-1
CME Note: Full asymmetric halo CME seen to the SW in all three coronagraphs. Source is a large eruption and several M-class flares from Active Region 13664, including a long-duration M4.9 flare associated with the post-eruptive arcades. Widely opening field lines and a rising loop of ejecta seen starting at 2024-05-13T08:10Z in SDO AIA 193/171. Ejecta and post-eruptive brightening and arcades seen at 08:43Z in SDO AIA 131/304. Post eruptive arcades seen at 11:15Z in SDO AIA 171/193/304. Possible arrival signature is characterized by a small but distinct shock: Bt increasing from around 4nT->7.5nT, with a minimal but noticeable bump in temperature, density, and speed. It is possibly the arrival of the shock front of this CME.
