Solar Radiation Storm Forecast for Jan 02-Jan 04 2026

Jan 02 Jan 03 Jan 04
S1 or greater 20% 10% 10%

Rationale: There is a slight chance for S1 (Minor) or greater solar
radiation storms over 02-04 Jan due to multiple complex regions on the
solar disk.

C. NOAA Radio Blackout Activity and Forecast

No radio blackouts were observed over the past 24 hours.

Radio Blackout Forecast for Jan 02-Jan 04 2026

Jan 02 Jan 03 Jan 04
R1-R2 55% 55% 55%
R3 or greater 20% 20% 20%

Rationale: R1-R2 (Minor-Moderate) radio blackouts are likely over 02-04,
with a slight chance for R3 (Strong), primarily due to flare potential
from Regions 4325 and 4324.

A. NOAA Geomagnetic Activity Observation and Forecast

The greatest observed 3 hr Kp over the past 24 hours was 2 (below NOAA
Scale levels).
The greatest expected 3 hr Kp for Jan 05-Jan 07 2026 is 3.67 (below NOAA
Scale levels).

Rationale: No G1 (Minor) or greater geomagnetic storms are expected.

B. NOAA Solar Radiation Activity Observation and Forecast

Solar radiation, as observed by NOAA GOES-18 over the past 24 hours, was
below S-scale storm level thresholds.

Solar Radiation Storm Forecast for Jan 05-Jan 07 2026

Jan 05 Jan 06 Jan 07
S1 or greater 10% 10% 10%

Rationale: There remains a slight chance for S1 (Minor) or greater solar radiation storms over 05-07 Jan.

R1-R2 50% 50% 50%
R3 or greater 10% 10% 10%

Rationale: There exists a chance for R1-R2 (Minor-Moderate) radio
blackouts, with a slight chance for R3 (Strong), over 05-07 Jan.

A. NOAA Geomagnetic Activity Observation and Forecast

The greatest observed 3 hr Kp over the past 24 hours was 2 (below NOAA
Scale levels).
The greatest expected 3 hr Kp for Jan 08-Jan 10 2026 is 5.00 (NOAA Scale
G1).

Rationale: G1 (Minor) or greater geomagnetic storms are anticipated on
09 Jan due to a coronal high speed stream interacting with a potential
glancing blow from a CME that left the Sun on 06 Jan.
