SIDC FORECAST (valid from 1230UT, 01 Apr 2022 until 03 Apr 2022) 
SOLAR FLARES  : C-class flares expected, (probability >=50%) 
GEOMAGNETISM  : Active conditions expected (A>=20 or K=4) 
SOLAR PROTONS : Quiet 
PREDICTIONS FOR 01 Apr 2022  10CM FLUX: 149 / AP: 020 
PREDICTIONS FOR 02 Apr 2022  10CM FLUX: 152 / AP: 016 
PREDICTIONS FOR 03 Apr 2022  10CM FLUX: 157 / AP: 016
COMMENT: 

... The greater than 2 MeV electron flux remained below the 1000 pfu alert threshold the past 24 hours. It is expected to increase over the next 24 hours, depending any possible impact from the CME associated with the X1.3 flare from March 30th. The greater than 2 MeV electron fluence was at nominal levels the past 24 hours. It is expected to remain at about levels over the next 24 hours.

Lead Time: 2.15 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.

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.
