04:24 МСК - произошла сильнейшая вспышка
X5.4
SUMMARY: X-ray Event exceeded X1
Begin Time: 2012 Mar 07 0002 UTC
Maximum Time: 2012 Mar 07 0024 UTC
End Time: 2012 Mar 07 0040 UTC
X-ray Class: X5.4
Location: N17E29
NOAA Scale: R3 - Strong
Potential Impacts: Area of impact consists of large portions of the sunlit side of Earth, strongest at the sub-solar point.
Radio - Wide area blackout of HF (high frequency) radio communication for about an hour.
И на данный момент до Земли дошла волна солнечного ветра, выпущенная ранее, что вызвало умеренную магнитную бурю G2
ALERT: Geomagnetic K-index of 6
Threshold Reached: 2012 Mar 07 0848 UTC
Synoptic Period: 0600-0900 UTC
Active Warning: Yes
NOAA Scale: G2 - Moderate
Potential Impacts: Area of impact primarily poleward of 55 degrees Geomagnetic Latitude.
Induced Currents - Power grid fluctuations can occur. High-latitude power systems may experience voltage alarms.
Spacecraft - Satellite orientation irregularities may occur; increased drag on low Earth-orbit satellites is possible.
Radio - HF (high frequency) radio propagation can fade at higher latitudes.
Aurora - Aurora may be seen as low as New York to Wisconsin to Washinton state.
Возможны нарушения радиосвязи и сбои в работе навигационного оборудования, а также ошибки ориентации низкоорбитальных спутников. Полярное сияние - возможно даже в Нью-Йорке и Вашингтоне!
