CCMC CME Scoreboard
Prediction for CME (2026-08-16T19:48:00-CME-001)
CME Observed Time: 2026-08-16T19:48ZDONKI Link: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/48119/-1
CME Note: CME first seen to the W in SOHO LASCO C2 starting at 2026-08-16T20:03Z. It is also seen to the W in SOHO LASCO C3 and GOES CCOR-1 and to the NE in STEREO A COR2. The majority of this CME was missed in real time by SOHO LASCO C3 due to a data gap between downlinks. This CME is associated with a C8.2 class flare from AR 14506 (N10W42) that peaked at 2026-08-16T19:28Z. The flare is best seen in SDO AIA 131.
CME was not detected at Earth.

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.
