Title: Space Weather
Post by: Wrightwood on Jan 22, 12, 11:15:01 PM

Space Weather Message Code: SUMXM5
Serial Number: 85
Issue Time: 2012 Jan 23 0622 UTC

SUMMARY: X-ray Event exceeded M5
Begin Time: 2012 Jan 23 0338 UTC
Maximum Time: 2012 Jan 23 0359 UTC
End Time: 2012 Jan 23 0434 UTC
X-ray Class: M8.7
Optical Class: 1n
Location: N28W20
NOAA Scale: R2 - Moderate

Comment: Region 1402

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

Potential Impacts: Area of impact centered primarily on sub-solar
point on the sunlit side of Earth. Limited blackout of HF radio
communication, loss of radio contact for tens of minutes.

Space Weather Message Code: WATA30
Serial Number: 94
Issue Time: 2012 Jan 23 1335 UTC

WATCH: Geomagnetic A-index of 30 or greater predicted
NOAA Scale: Periods reaching the G2 (Moderate) Level Likely
Valid for UTC Day: 2012 Jan 24



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

Potential Impacts: Area of impact primarily poleward of 55 degrees
Geomagnetic Latitude. High-latitude power systems may experience
voltage alarms; long-duration storms may cause transformer damage.
Satellite orientation irregularities may occur; possible changes in
satellite drag affect orbit predictions. HF radio propagation can
fade at higher latitudes, and aurora may be seen as low as New York,
Idaho, mid-Aleutians.

Space Weather Message Code: ALTPX3
Serial Number: 25
Issue Time: 2012 Mar 07 1417 UTC

ALERT: Proton Event 10MeV Integral Flux exceeded 1000pfu
Begin Time: 2012 Mar 07 1410 UTC
NOAA Scale: S3 - Strong

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

Potential Impacts: Radiation - Passengers and crew in high latitude, high altitude flights may experience increasing radiation exposures. Astronauts on EVA (extra-vehicular activity) are exposed to elevated radiation levels.
Spacecraft - Single-event upsets to satellite operations, noise in imaging systems, and slight reduction of efficiency in solar panels are likely.
Radio - Degraded or episodically blacked-out polar HF (high frequency) radio propagation.
