----

Predicted Arrival Time: 2023-04-29T13:00Z (-12.0h, +12.0h)
Confidence that the CME will arrive: 25.0%
Predicted geomagnetic storm max Kp range due to CME: 3.0 - 6.0
Prediction Method: Other (SIDC)
Prediction Method Note:

:Issued: 2023 Apr 28 1328 UTC
#--------------------------------------------------------------------#
# FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium)         #
#--------------------------------------------------------------------#
A partial halo Coronal Mass Ejection (CME) can be seen in LASCO/C2 images starting from yesterday 01:25 UT and has a change to become geo-effective. The estimated speed of the CME is 800 km/s and the arrival day is 29 Apr.

A partial halo CME automatically detected by CACTus at Apr 26 23:34 UT is a back-sided event.

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.

If you are looking for the official U.S. Government forecast for space weather, please go to NOAA's Space Weather Prediction Center (https://swpc.noaa.gov). This "Experimental Research Information" consists of preliminary NASA research products and should be interpreted and used accordingly.
