CME Observed Time: 2021-07-26T16:48ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/17393/-1
CME Note: Partial halo to the southwest in SOHO LASCO/C2, to the west in COR2A. Associated with an eruption from AR 12847 (near S30E00), visible in SDO AIA 171/193 beginning 2021-07-26T14:57Z.
CME was not detected at Earth.
Observed Geomagnetic Storm Parameters due to CME:
----
Predicted Arrival Time: 2021-07-28T17:00Z (-8.0h, +8.0h)
Confidence that the CME will arrive: 75.0%
Predicted geomagnetic storm max Kp range due to CME: 3.0 - 5.0
Prediction Method: Other (SIDC)
Prediction Method Note:
From SIDC Ursigram, 2021-07-27T12:37Z: A relatively slow coronal mass ejection was observed on July 26 around 17:00 UTC in SOHO/LASCO-C2 chronograph images. It is associated with a coronal dimming near the Catania sunspot group 23 (NOAA AR-2847) located around -35 degrees and longitude -02 degrees. At most, a glancing blow may be observed in the solar wind parameters near Earth on July 29 around noon (+/-12 hours).Lead Time: 28.12 hour(s)

CCMC
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.
