NOAA Scale for Geomagnetic Storms

• None (Kp=0, Ap=0). Inactive geomagnetic field.
• None (Kp=1, Ap=3). Very quiet geomagnetic field.
• None (Kp=2, Ap=7). Quiet geomagnetic field.
• None (Kp=3, Ap=15). Unsettled geomagnetic field.
• None (Kp=4, Ap=27). Active geomagnetic field.
• G1 (Kp=5, Ap=48). Minor geomagnetic storm.
• G2 (Kp=6, Ap=80). Major geomagnetic storm.
• G3 (Kp=7, Ap=140). Severe geomagnetic storm.
• G4 (Kp=8, Ap=240). Very severe geomagnetic storm.
• G5 (Kp=9, Ap=400). Extremely severe geomagnetic storm.

NOAA Scale for Solar Radiation Storms

• S1: Minor solar radiation storm.
• S2: Moderate solar radiation storm.
• S3: Strong solar radiation storm.
• S4: Severe solar radiation storm.
• S5: Extreme solar radiation storm.

NOAA Scale for Radio Blackouts

• R1: Minor radio blackout.
• R2: Moderate radio blackout.
• R3: Strong radio blackout.
• R4: Severe radio blackout.
• R5: Extreme radio blackout.
