September 11 Space Weather Alert from NOAA Warns of Solar Flare

NOAA

NOAA has issued several Space Weather Alerts for those who might be flying on high-altitude flights or on spaceships today or tomorrow.

On Wednesday a high intensity solar flare erupted from the sun and shot towards Earth. It may affect high frequency (HF) radios and electronics for an hour or so -- but what NOAA is specifically warning about is the unusual amount of " Proton 100MeV Integral Flux," which presents "increased biological risk to astronauts or passengers and crew in high latitude, high altitude flights."

It also puts satellite systems at risk if they suffer a direct hit.

For those who talk geek, here's the warning:

Space Weather Message Code: WARPC0
Serial Number: 78
Issue Time: 2014 Sep 10 2322 UTC

WARNING: Proton 100MeV Integral Flux above 1pfu expected
Valid From: 2014 Sep 10 2330 UTC
Valid To: 2014 Sep 11 2100 UTC
Warning Condition: Onset
Potential Impacts: An enhancement in the energetic portion of the solar radiation spectrum may indicate increased biological risk to astronauts or passengers and crew in high latitude, high altitude flights. Additionally, energetic particles may represent an increased risk to all satellite systems susceptible to single event effects. This information should be used in conjunction with the current Solar Radiation Storm conditions when assessing overall impact.

Space Weather Message Code: WARPX1
Serial Number: 433
Issue Time: 2014 Sep 10 2105 UTC

WARNING: Proton 10MeV Integral Flux above 10pfu expected
Valid From: 2014 Sep 10 2115 UTC
Valid To: 2014 Sep 11 2100 UTC
Warning Condition: Onset
Predicted NOAA Scale: S1 - Minor
Potential Impacts: Radio - Minor impacts on polar HF (high frequency) radio propagation resulting in fades at lower frequencies.
