Auroral Activity Extrapolated from NOAA POES

Instruments on board the NOAA Polar-orbiting Operational Environmental Satellite (POES) continually monitor the power flux carried by the protons and electrons that produce aurora in the atmosphere. SWPC has developed a technique that uses the power flux observations obtained during a single pass of the satellite over a polar region (which takes about 25 minutes) to estimate the total power deposited in an entire polar region by these auroral particles. The power input estimate is converted to an auroral activity index that ranges from 1 to 10.

Kp - Planetary K-index, averaged over past 3 hours and tends to be a measure of current conditions

Ap - Planetary A-index, 24-hour average and represents overall geomagnetic field conditions for the UTC day

HF Noise - Approximate "S-meter" noise level <10 MHz

Aurora- Approximate level of auroral activity


Solar Wind-averages 350-450 km/sec and density <10 p/cm^3 >500 km/sec or high density can trigger geomagnetic activity

Shock Wave- from a solar flare or Coronal Mass Ejection (CME) arrives at the Earth about 55 hours after the solar event.


Solar Flare Classifications

Flare ClassType of FlareHF Radio EffectsResulting Geomagnetic Storm
A Very small None None
B Small None None
C Moderate * Low absorption * Active to Minor
M Large * High absorption * Minor to Major
X Extreme * Possible blackout * Major to Severe


(*) - Conditions cited if Earth is in trajectory of flare emissions

Flare class further rated from 1-9, ex. M1, M2, M3 ... M9

The larger the number, the larger the flare within that class

An X7 - X9 is considered a "Grand daddy" flare. Only a few have occured over the past 30 years, causing total dispruption to communications, huge aurora's, power grid failures, etc.
Radio and x-ray emissions from a flare effect the Earth for the duration of the solar event, usually 30 minutes or less.

Earth is 8 light-minutes from the Sun.


Sunspot/Active Region Classifications

Sunspot Class Description of the Active Region Potential for Flare Activity
Alpha Unorganized, unipolar magnetic fields Little threat, but watched for growth
Beta Bipolar magnetic fields between sun spotsC class flares and possible large M class
Delta Strong, compact bipolar fields between spots High potential for a M or X class major flare Major Flare Alert issued
