Lots of solar flares

Space Weather report solar activity is high. In just 48 hours, monster sunspot AR2192 has produced a series of seven M-class solar flares of increasing intensity

The eruptions crossed the threshold into X-territory with an X1-class flare on Oct. 22nd. NASA’s Solar Dynamics Observatory recorded a powerful flash of extreme UV radiation in the sunspot’s magnetic canopy at 14:30 UT.

Remarkably, not one of the explosions so far has hurled a significant CME toward Earth. The primary effect of the flares has been to ionize Earth’s upper atmosphere, causing a series of short-lived HF radio communications blackouts. Such blackouts may be noticed by amateur radio operators, aviators, and mariners.

Earth-effects could increase in the days ahead. AR2192 has an unstable ‘beta-gamma-delta’ magnetic field that harbors energy for powerful explosions, and the active region is turning toward Earth. NOAA forecasters estimate at 65% chance of M-class flares and a 20% chance of X-flares during the next 24 hours.

This could be an interesting propagation week for both amateur radio operators and commercial broadcasters.  According to Space Weather, sunspot AR2192 has produced at least 7 M-class solar flares.  More flares may be on the way.  So far, the only effect has been a temporary interruption of HF communications lasting only a few hours.

Space Weather Forecasting Centre officially opened | Southgate Amateur Radio News


Page last updated on: Wednesday, October 8, 2014 Share on facebookShare on twitterShare on emailShare on printMore Sharing Services.  The Space Weather Forecasting Centre officially opened on October 8, 2014. Greg Clark, Minister for Universities, Science and Cities, opened the UK’s only dedicated space weather forecast centre.  The Met Office Space Weather Centre, based at the Met Office’s headquarters in Exeter, is the culmination of more than three years work to combine the space weather resources and scientific expertise of the UK and USA and was made possible by £4.6 million funding from Government .It is operational 24/7 providing space weather forecasts and developing an early warning system aimed at protecting critical infrastructure from the impacts of space weather. Universities, Science and Cities Minister Greg Clark said:”The Met Office Space Weather Centre is a clear demonstration of how the UK is a world leader in space weather. Not only will it help us to guard against the impact of space weather, but its capabilities will mean benefits for British businesses like those in the space industry and the wider economy.”Met Office Space Weather Business Manager Mark Gibbs said: “The Met Office Space Weather Operations Centre is the culmination of more than three years’ work drawing on the collective resources and expertise of the UK and USA. It’s a new, emerging and exciting area of science where understanding is growing rapidly.”Space weather is an all encompassing term covering the near-Earth impact of solar flares, geomagnetic storms and coronal mass ejections CMEs from the sun. The impact these have on Earth is becoming ever more important as we become more reliant on technology.”Press releasehttp://www.metoffice.gov.uk/news/releases/archive/2014/space-weatherMet Office Space Weatherhttp://www.metoffice.gov.uk/publicsector/emergencies/space-weather Share this page Follow usShare on facebookShare on twitterShare on emailShare on printMore Sharing Services4Share on facebookShare on twitterShare on rss  Advertisement

Stratospheric radiation rebounds following CME strike

Stratospheric radiation levels are returning to normal, according to a Space Weather Buoy launched on Sept. 28th by students in California.

This follows a mid-September drop in ionizing radiation caused, ironically, by a strong solar storm and CME strike.

Data and a discussion of the phenomenon may be found on today’s edition of http://spaceweather.com

——————————————–

California students who launched what they called “a Space Weather Bouy” on 28 September 2014, claim “stratospheric radiation levels are returning to normal” following a strong solar disturbance and a CME strike.  Visit http://spaceweather.com for details.  It’s nice to see students engage in real-time space research.

Space Weather, HF Radio Propagation – The Interview on ‘Ham Radio Now’ | AmateurRadio.com


Why would an amateur radio operator be interested in space weather? Is it worth the time and resources to forecast propagation, in the daily operation of a (Why should the average #hamradio operator care about propagation and #spaceweather?

Source: www.amateurradio.com

An excellent interview with Tomas Hood (NW7US), the propagation and space weather columnist for “CQ Amateur Radio” Magazine and “The Spectrum Monitor” Magazine.  Gary and Tomas discuss how scientists forecast space weather and how amateur radio operators can make predictions on propagation and enhance their station operations.  For details, visit nw7us.heliophile@gmail.com.  Aloha de Russ (KH6JRM).
