M6.5 solar flare erupted from Earth facing Region 1719 - CME produced

M6.5 solar flare erupted from Earth facing Region 1719 - CME produced

A moderate, yet strongest this year so far, solar flare measuring M6.51 erupted on April 11, 2013 at 07:16 UTC. The source of this event is Active Region 1719 located almost in the center of the disk and with Beta-Gamma magnetic field capable of producing strong solar flares.

The event started at 06:55, peaked at 07:16 and ended at 07:29 UTC. A Type II and Type IV radiation emissions were associated with the event indicating a major eruption on the sun with strong coronal ejection and solar radiation.

Additionally, a 10cm radio burst was associated with the event. 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.

Our planet is in the line of fire from AR 1719 and today's CME is headed our way. A geomagnetic storm category G2 is forecasted for April 13, 2013:

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 Washington state.

Space Weather Message Code: WARPC0
Serial Number: 67
Issue Time: 2013 Apr 11 1403 UTC

EXTENDED WARNING: Proton 100MeV Integral Flux above 1pfu expected
Extension to Serial Number: 66
Valid From: 2013 Apr 11 0935 UTC
Now Valid Until: 2013 Apr 11 2100 UTC
Warning Condition: Persistence

Potential Impacts: An enhancement in the energetic portion of the solar radiation spectrum may indicate increased biological risk to astronauts or passengers and crew in high latitude, high altitude flights. Additionally, energetic particles may represent an increased risk to all satellite systems susceptible to single event effects. This information should be used in conjunction with the current Solar Radiation Storm conditions when assessing overall impact.

ALERT: Type II Radio Emission
Begin Time: 2013 Apr 11 0702 UTC
Estimated Velocity: 1370 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.

ALERT: Type IV Radio Emission
Begin Time: 2013 Apr 11 0702 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.

ALERT: X-Ray Flux exceeded M5
Threshold Reached: 2013 Apr 11 0711 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.

Serial Number: 574
Issue Time: 2013 Apr 11 0937 UTC

SUMMARY: 10cm Radio Burst
Begin Time: 2013 Apr 11 0658 UTC
Maximum Time: 2013 Apr 11 0702 UTC
End Time: 2013 Apr 11 0718 UTC
Duration: 20 minutes
Peak Flux: 470 sfu
Latest Penticton Noon Flux: 148 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.

Sunspots

There are currently 9 numbered active regions on the disk. Two of them have Beta-Gamma magnetic field, those are Regions 1718 and 1719 (the source of todays M6.5 event). Five regions have Beta magnetic field - 1711, 1713, 1717, 1721 and 1722. The remaining two, Regions 1714 and 1716, have Alpha magnetic field.

NOAA SWPC forecasters estimated 20% chance for an M-class solar flare, and 1% chance for X-class event today.

I love solar flares and warm weather :) I'd be happier in a Stone Age if that means i never have to shovel snow out of my driveway ever again :D But seriously. Premonitions and coincidences are just idle pleasures of the brain, having no real significance. Indulging in conspiracy theories are just a waste of your brain power to create something of actual value for humanity.....

M9 is getting closer

I heard someone predicted that when North Korea launches an nuclear attack, a massive solar flare will follow and plunge our world back to stone age. Hmmmm...sounds like it is all coming together.

Don't worry everything is a plan and is just prefect :) "We" are not alone...Take care.

Angel (@nanoduck) 7 years ago

Wondering what will hapen if the solar storm hit the M9 ? N5?
