Please read the following from the NOAA Space Weather Prediction Center:



**************************************************************************
Space Weather Message Code: WARPC0
Serial Number: 49
Issue Time: 2012 Jan 23 1633 UTC

EXTENDED WARNING: Proton 100MeV Integral Flux above 1pfu expected
Extension to Serial Number: 48
Valid From: 2012 Jan 23 0449 UTC
Now Valid Until: 2012 Jan 23 2100 UTC
Warning Condition: Persistence

NOAA Space Weather Scale descriptions can be found at
www.swpc.noaa.gov/NOAAscales

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.
