The Sun is Angry, Many Space Weather Alerts, Possible Earth Directed CME!

Over the last day NOAA has issued many Space Weather Alerts due to Giant sunspot AR1944. It erupted on Jan 7th 1832 UT, This was associated with an X1-class solar flare. It does appear to have produced a Coronal Mass Ejection (CME). If this is the case there is no doubt it would be headed in Earth’s Direction.

NOAA is predicting high probability of M, and X class storms as well as proton events over the next day.

In this image you can see the huge sunspot AR1944 directly in the center. A CME from this spot would most certainly impact Earth

Issue Time: 2014 Jan 08 0415 UTC

ALERT: Type II Radio Emission
Estimated Velocity: 697 km/s

Description: Type II emissions occur in association with eruptions on the sun and typically indicate a coronal mass ejection is associated with a flare event.


Issue Time: 2014 Jan 07 1925 UTC

ALERT: Type II Radio Emission
Estimated Velocity: 1064 km/s

Description: Type II emissions occur in association with eruptions on the sun and typically indicate a coronal mass ejection is associated with a flare event.


Issue Time: 2014 Jan 07 1533 UTC

ALERT: Electron 2MeV Integral Flux exceeded 1000pfu
Threshold Reached: 2014 Jan 07 1525 UTC
Station: GOES13

Potential Impacts: Satellite systems may experience significant charging resulting in increased risk to satellite systems.


Issue Time: 2014 Jan 07 1016 UTC

ALERT: X-Ray Flux exceeded M5
Threshold Reached: 2014 Jan 07 1012 UTC
NOAA Scale: R2 – Moderate

Potential Impacts: Area of impact centered on sub-solar point on the sunlit side of Earth. Extent of blackout of HF (high frequency) radio communication dependent upon current X-ray Flux intensity. For real-time information on affected area and expected duration


Issue Time: 2014 Jan 06 0910 UTC

ALERT: Type IV Radio Emission
Begin Time: 2014 Jan 06 0653 UTC

Description: Type IV emissions occur in association with major eruptions on the sun and are typically associated with strong coronal mass ejections and solar radiation storms.
