ANOTHER SOLAR FLARE: Active sunspot AR2205 unleashed another strong solar flare today, an impulsive M7-class explosion that peaked around 0947 UT. Radio emissions suggest that a CME raced away from the blast site at 800 km/s (1.8 million mph). Because the sunspot is not facing Earth, the CME should miss our planet. NOAA forecasters estimate a 55% chance of more M-flares in the next 24 hours. Space Weather Message Code: WARK04 Serial Number: 2367 Issue Time: 2014 Nov 05 1555 UTC EXTENDED WARNING: Geomagnetic K-index of 4 expected Extension to Serial Number: 2366 Valid From: 2014 Nov 04 0815 UTC Now Valid Until: 2014 Nov 06 0100 UTC Warning Condition: Persistence Potential Impacts: Area of impact primarily poleward of 65 degrees Geomagnetic Latitude. Induced Currents - Weak power grid fluctuations can occur. Aurora - Aurora may be visible at high latitudes such as Canada and Alaska. Space Weather Message Code: ALTTP2 Serial Number: 980 Issue Time: 2014 Nov 05 1015 UTC ALERT: Type II Radio Emission Begin Time: 2014 Nov 05 0943 UTC Estimated Velocity: 816 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. Space Weather Message Code: SUMXM5 Serial Number: 127 Issue Time: 2014 Nov 05 1004 UTC SUMMARY: X-ray Event exceeded M5 Begin Time: 2014 Nov 05 0926 UTC Maximum Time: 2014 Nov 05 0947 UTC End Time: 2014 Nov 05 0955 UTC X-ray Class: M7.9 Location: N16E63 NOAA Scale: R2 - Moderate Potential Impacts: Area of impact centered primarily on sub-solar point on the sunlit side of Earth. Radio - Limited blackout of HF (high frequency) radio communication for tens of minutes. Space Weather Message Code: SUM10R Serial Number: 641 Issue Time: 2014 Nov 05 0957 UTC SUMMARY: 10cm Radio Burst Begin Time: 2014 Nov 05 0940 UTC Maximum Time: 2014 Nov 05 0941 UTC End Time: 2014 Nov 05 0946 UTC Duration: 6 minutes Peak Flux: 229 sfu Latest Penticton Noon Flux: 129 sfu Description: A 10cm radio burst indicates that the electromagnetic burst associated with a solar flare at the 10cm wavelength was double or greater than the initial 10cm radio background. This can be indicative of significant radio noise in association with a solar flare. This noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications. Space Weather Message Code: ALTXMF Serial Number: 240 Issue Time: 2014 Nov 05 0946 UTC ALERT: X-Ray Flux exceeded M5 Threshold Reached: 2014 Nov 05 0944 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.
