The greatest observed 3 hr Kp over the past 24 hours was 3 (below NOAA
Scale levels).
The greatest expected 3 hr Kp for Mar 30-Apr 01 2023 is 4.00 (below NOAA
Scale levels).

Mar 30 Mar 31 Apr 01
Rationale: No G1 (Minor) or greater geomagnetic storms are expected. No
B. NOAA Solar Radiation Activity Observation and Forecast
Solar radiation, as observed by NOAA GOES-16 over the past 24 hours, was
below S-scale storm level thresholds.
Solar Radiation Storm Forecast for Mar 30-Apr 01 2023
Mar 30 Mar 31 Apr 01
S1 or greater 10% 5% 5%
Rationale: The greater than 10 MeV proton flux is expected to continue
at near background levels through 01 Apr. However, there is a slight
chance for an S1 (Minor) solar radiation storm on 30 Mar, primarily due
to the
favorable location and slight risk of a solar energetic proton event
from Region 3256.
C. NOAA Radio Blackout Activity and Forecast
Radio blackouts reaching the R2 levels were observed over the past 24
Radio Blackout Forecast for Mar 30-Apr 01 2023
Mar 30 Mar 31 Apr 01
R1-R2 25% 10% 10%
R3 or greater 10% 5% 5%
Rationale: There is a chance for R1-R2 (Minor-Moderate) radio blackouts
on 30 Mar, then a slight chance for R1-R2 blackouts on 31 Mar - 01 Apr.
There is a slight chance for R3 (Strong) or greater radio blackouts on
.
