CME Note: This somewhat asymmetric bright CME is visible to the SE in STEREO A COR2 for a few frames before a usual overnight data gap and in SOHO LASCO C2/C3 and GOES CCOR-1. Its source is a significant filament eruption with associated brightening/dimming starting around 2026-03-22T15:30Z, followed by high rising post-eruptive arcades, as seen in GOES SUVI 304, 284, and 195 centered around S20E15, south of Active Region 14398, and seen as ejecta and opening of field lines seen in STEREO A EUV 195/403 on/close to the SE limb. It appears that there may be some SE deflection/directionality to it,. as it erupts and progresses outward in the GOES SUVI 284 field of view. There is a bright bulk front and a wider faint shock front seen in all three coronagraphs. | Arrival information: Increase in B_total from 3.88 nT to 7.21 nT increasing to a maximum of 10.19 nT. Solar wind speed increased from roughly 530 km/s to roughly 600 km/s. Minor increase in solar wind temperature and density were also observed. This signature is likely associated with the arrival of CME with ID 2026-03-22T16:23:00-CME-001 which was modeled to impact missions near Earth at 2026-03-25T08:55Z (+/- 7 hours).

Rules of the Road: CCMC requests that users notify the CCMC, CME
model/technique developers and submitting forecasters/researchers before
performing event and validation studies with data from the CME Arrival
Time Scoreboard. It is recommended that such studies be performed with
the knowledge and collaboration of developers and submitting
forecasters/researchers.
