A. NOAA Geomagnetic Activity Observation and Forecast
The greatest observed 3 hr Kp over the past 24 hours was 1 (below NOAA
Scale levels).
The greatest expected 3 hr Kp for May 07-May 09 2026 is 4.33 (below NOAA
Scale levels).

Rationale: There is a chance for isolated periods of G1-G2
(Minor-Moderate) geomagnetic storming late on 07 May through 08 May due
to the onset of +CH HSS influences.
B. NOAA Solar Radiation Activity Observation and ForecasRationale: There is a slight chance for isolated R1-R2 (Minor-Moderate)
radio blackouts on 07 May. Probabilities increase beginning 08 May as up
to two active regions near L=330 rotate into view from beyond the
eastern limb. ConsideringRationale: There is a slight chance for isolated R1-R2 (Minor-Moderate)
radio blackouts on 07 May. Probabilities increase beginning 08 May as up

radio blackouts on 07 May. Probabilities increase beginning 08 May as up
to two active regions near L=330 rotate into view from beyond the
eastern limb. Considering the size of these regions and recent far-side
eruptions seen in coronagraph imagery, solar activity is expected to
increase 08-09 May with a chance for R1-R2 (Minor-Moderate) radio
blackouts, and a slight chance for R3 (Strong or greater) events.
