Major solar flare measuring X1.0 erupted from Region 2017

Major solar flare measuring X1.0 erupted from Region 2017

Major solar flare measuring X1.0 erupted from Region 2017 on March 29, 2014. This event started on 17:35, peaked at 17:48 and ended at 17:54 UTC. Area of impact consists of large portions of the sunlit side of Earth, strongest at the sub-solar point. Wide area blackout of HF (high frequency) radio communication for about an hour.

A 10 cm Radio burst event with peak flux of 360 sfu was observed from 17:45 - 17:48 UTC.

Additionally, a Type II radio sweep was observed at 17:53 UTC with estimated velocity 4 508 km/s! Type II emissions occur in association with eruptions on the sun and typically indicate a coronal mass ejection is associated with a flare event.

This region already had 2 moderately strong eruptions in last 24 hours - M2.0 19:18 UTC and M2.6 at 23:51 UTC on March 28, 2014.

Most of the CME is directed north, but there appears to be a faint Earth-directed component that could deliver a glancing blow to our planet's magnetic field on April 1/2.

Space Weather Message Code: SUM10R

Issue Time: 2014 Mar 29 1821 UTC

SUMMARY: 10cm Radio Burst
Begin Time: 2014 Mar 29 1745 UTC
Maximum Time: 2014 Mar 29 1746 UTC
End Time: 2014 Mar 29 1748 UTC
Duration: 3 minutes
Peak Flux: 360 sfu
Latest Penticton Noon Flux: 146 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.

Now watch for major earthquake or volcanic eruption to take place in the next two days
