MST). This is the largest of seven major flares observed in this large and complex sunspot cluster since it emerged as a major flare producer on 15 January. A strong (S3) radiation storm began soon after this flare. Radiation storms on the NOAA scale are based on proton measurements at >10 MeV. However, this radiation storm is particularly interesting because of the influx of high energy protons (>100 MeV). In fact, this radiation storm, based on the >100 MeV protons, is the strongest since October 1989. A rare, strong ground-level event (GLE) was also observed. GLEs are increases in the ground-level neutrons detected by neutron monitors and are generally associated with very high energy protons (>500 MeV). Elevated neutrons at ground level means there are high fluxes of energetic protons near Earth. High energy radiation storms can be particularly hazardous to spacecraft, and to communication, navigation, and aviation operations at high latitudes. Active Region 720 is now located near the northwest limb of the Sun; consequently, most of the ejecta from today's coronal mass ejection will not impact the geomagnetic field. However G1 conditions are still possible on 22 and 23 January. Further major flare activity is possible from Region 720 before it rotates to the far side of the Sun on 22 - 23 January. Data used to provide space weather services are contributed by NOAA, USAF, NASA, NSF, USGS, the International Space Environment Services and other observatories, universities, and institutions.

Interesting post which makes me curious about the impact on normal radio communications. I know they can cause radio blackouts, but is there a group of services they tend to interfere more with (HF as used by aircraft etc.)? Since you last informed us on this I have found the site http://www.spaceweather.com/ to be useful to a total novice like me, as they explain a lot of the terms (to say nothing of the very lovely pictures on the site). -- John Mail sent to the reply address will be binned automatically.

We have discussed solar flares before in the newsgroups and the effects that it has on communications, aviation (radiation hazard as well as communications and navigation hazard). There are various scales and if we every reach a Level 5 then we are in serious trouble. I will try and dig out a few more links regards John Back to top Fraser Guest Posted: Sun Jan 23, 2005 4:38 pm    Post subject: Re: **** STRONG SOLAR FLARE AND RADIATION STORM **** "John Reid" <news (AT) jazza (DOT) demon.co.uk> wrote Quote: It is written in message 41f2ebc0$0$16974$ed2e19e4 (AT) ptn-nntp-reader04 (DOT) plus.net> that Fraser sayeth : Anybody with a good scientific brain tell me if this would be why I saw quite vivid Northern Lights from my home in Dunblane last night (Friday) ?

A very interesting site indeed - none of my sightings were quite as spectacular as the ones photographed but it at least gives me some evidence to show my dad, who didn't believe me, and stood out in the back garden for 20 minutes waiting to see something which never appeared!

Fraser, I passed Dunblane on Friday evening and the Norther Lights were spectacularly visible. I actually stopped on the Auchterarder bypass and watched the display for a while. Very spectacular. Shame your father didn't see anything as it lasted though to about 7am on Saturday . You can of course sign up for e mail alerts of probable activity. This one was accurately forecast on Wednesday.
