Popping M-class flares – M3.5 solar flare erupted at 15:30 UTC

Region 1618 is popping one M-class solar flare after another. On November 21, 2012 it erupted with M3.5 solar flare peaking at 15:30 UTC. This is second M-class solar flare of the day, the second M-class from Region 1618 today, and fourth M-class solar flare in last 24 hours.

A Type II and IV Radio Emissions were reported. Type IV Radio Emissions occur in association with major eruptions on the Sun and are typically associated with strong Coronal Mass Ejections (CME) and solar radiation storms.

A 10cm Radio Burst (TenFlare) was associated with the event. This can be indicative of significant radio noise in association with a solar flare. The more intense solar flares are associated with TenFlares. Almost all major flares are associated with them. Generally, the greater the intensity of the burst of noise observed at the 10.7 cm wavelength band, the more significant the flare is said to be.

NOAA/SWPC forecasters estimated there was 70% chance of an M-class event today, and 15% chance of an X-class event.

Region 1618 is now ten times wider than Earth. It’s continually growing and still has Beta-Gamma magnetic configuration capable of producing strong solar flares. It is now located in the center of the solar disk, in perfect position for Earth directed Coronal Mass Ejections (CME).

Serial Number: 569
Issue Time: 2012 Nov 21 1722 UTC

SUMMARY: 10cm Radio Burst
Begin Time: 2012 Nov 21 1521 UTC
Maximum Time: 2012 Nov 21 1523 UTC
End Time: 2012 Nov 21 1559 UTC
Duration: 38 minutes
Peak Flux: 200 sfu
Latest Penticton Noon Flux: 141 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.

ALERT: Type IV Radio Emission
Begin Time: 2012 Nov 21 1531 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.

  1. Could someone please tell me how long it takes for the effects to become visible on earth. Also does/could the beta aspect effect humans in relation to sleep cycles but especially to drowsiness?

    1. In short: average time of arrival is 2-3 days. Yes.

      Longer version: If there is Coronal Mass Ejection (CME) generated it takes some time to get to Earth. By some scientists 2-3 days should be average, but in many cases a much shorter time of arrival was recorded. This video explains part about solar flare classes https://watchers.news/2012/11/21/x-class-a-guide-to-solar-flares/. This article explains more on effects on humans https://watchers.news/2012/07/14/solar-storms-and-pineal-gland-riding-the-power-wave/, check related posts on second one for more about that.
