The earth's magnetic field is about 500 milligauss (1/2 gauss). The argument is that the earth's field is DC and power line radiation is AC which might have different effects on the body. Now presumably the earth's field is benign (after all, our ancestors have been evolving in it for millions of years.) I have a hard time believing that AC fields 100 times weaker are all that bad.

The first began at 20:17 UT, peaked at 20:31 UT and ended at 20:34 UT on 21 March. It was located at S13E29 and attained a class X1.0/1N rating. It was associated with rather weak radio bursts and had a low integrated x-ray flux. This event was impulsive. No sweeps were observed. The second major flare began at 23:35 UT, peaked at 23:44 UT on 21 March, and ended at 00:01 UT on 22 March. This event attained a class M5.4/2B rating and was associated with a fairly strong Type IV event. However, this flare was impulsive as well. Region 6555 (now located at S24E30) remains impressive and is the largest and most complex region currently visible. Spot counts have increased to 75 in this region, which still maintains a magnetic beta configuration. POTENTIAL TERRESTRIAL IMPACT ASSESSMENT The first major flare (the X-class event) will not have a terrestrial impact. It was a high-amplitude event in x-rays, but has not produced any significant radio emissions and was quite impulsive. The second major flare is still being studied and the potential impacts will not be fully known until later on 22 March. It presently appears as though a small risk exists for a light terrestrial impact (mostly over the higher latitudes) sometime on 24 March. However, this flare was not radio rich. The only truly noteworthy phenomena associated with this flare was the moderate to strong intensity Type IV which accompanied the flare. The integrated x-ray flux of this flare was low. So there is a higher probability that no terrestrial impacts will be observed. A more accurate assessment will be released on 22 March after all of the data has been analyzed. Isolated major flaring will likely continue from Region 6555 over the next 24 to 72 hours. Minor M-class flaring will certainly continue at a fairly frequent rate. Associated minor SIDs/SWFs could cause momentary disruptions in HF radio communications. A total of seven SID's/SWF's were observed (some are unconfirmed at the present time) on 21 March, associated with the fairly frequent M-class flaring from Region 6555. A period of minor geomagnetic storming occurred between 12:00 UT and 15:00 UT over middle latitudes. This period was preceded by a sudden impulse which occurred near 06:00 UT on 21 March over some middle latitude stations. Locally, the only significant perturbation occurred at 13:45 UT and was rated as a minor storm level fluctuation with a fairly rapid rise-time and slow decay. High latitudes experienced active to severe storming during this period. Some high latitude auroral storming was also noted in conjunction with this increased geomagnetic activity. It is difficult to pinpoint the cause of this activity, as there were several events which may have been responsible. However, at the present time, it appears as though the major class M6.7/2B flare of 19 March is most likely responsible. Auroral activity remained confined to the high and northerly middle latitudes. HF radio conditions during this period of storm activity was degraded to generally poor levels over middle latitudes and very poor levels over the high latitudes. Conditions improved rapidly after 16:00 UT, as did geomagnetic activity over the middle latitudes. A bulletin stating the potential impacts of the last major M-class flare will be issued later on 22 March. The POTENTIAL MAJOR SOLAR FLARE WARNING and the POTENTIAL SATELLITE PROTON EVENT WARNING remain in effect. Geomagnetic activity should remain at unsettled to active levels over the next 24 hours. Auroral activity will remain at low to moderate levels over the middle and/or northerly middle latitudes on 22 March, with moderate to high levels of activity likely over the high latitudes. Low latitudes will not witness any auroral activity. ** End of Alert ** ------------------------------ Date: 22 Mar 91 19:57:23 GMT From: news-mail-gateway@ucsd.edu Subject: MAJOR SOLAR FLARE ALERT - 22 MARCH - STRANGE TYPE IV WITH 21 MARCH To: info-hams@ucsd.edu -- MAJOR SOLAR FLARE ALERT -- MARCH 22, 1991 Flare Event Summary Potential Impact Assessment -------- MAJOR ENERGETIC EVENT SUMMARY Another major flare erupted from Region 6555 at a location of S25E35. This event began at 08:33 UT, peaked at 08:40 UT and ended at 09:19 UT on 22 March. There was a tenflare with this event, rated at 870 s.f.u.. Also, a 245 MHz burst was observed at an intensity of 12,000 s.f.u. No sweeps were observed. The flare was fairly impulsive and had a low integrated x-ray flux. The event attained a class M6.3/1B rating. POTENTIAL TERRESTRIAL IMPACT ASSESSMENT No terrestrial impacts are expected with this latest major flare. It had some moderately strong radio emissions but was not associated with any sweeps and was an impulsive event. The most strange event which is really turning heads is the major class 5.4/2B flare of 21 March (at 23:44 UT). This event was not particularly unusual as far as the flare itself goes, but the radio emissions observed were very odd indeed. The flare was associated with a strong Type IV emission which drifted from low to high frequencies (it should have been the other way around). The emission increased in intensity with time and reached very brilliant levels. The event is STILL IN PROGRESS at the time of this writing. It has been categorized a continuum Type IV emission. It is perhaps one of the strangest emissions observed in seven years. Something is vigorously exciting the electrons over that region, but no one knows what it might be. The flare itself was not extraordinary. In fact, it was rather "average". There is a possibility that a Type II could have occurred with the 23:44 UT flare of 21 March. There is uncertainty regarding this due to the fact that the Type IV drifted from low to high frequencies and may have "swallowed" the Type II emission. So it is certainly possible that a Type II could have occurred with this event (it would normally be observed with a Type IV continuum emission as intense as this one has been). This event is very difficult to assess as far as potential terrestrial impacts are concerned. The flare itself was impulsive and of rather low intensity. But the wierd long duration Type IV continuum emission together with the possible occurrence of a Type II is raising questions. We currently believe that a low to moderate risk exists for increased terrestrial activity late on 23 March or on 24 March. There is a slightly higher probability that no terrestrial impacts will occur, but these predictions are not associated with high confidence levels. A Potential Geomagnetic Storm Warning may be issued on 23 March just to cover the "bases." Analysis of this odd event will continue. Major flaring is expected to continue from Region 6555. Terrestrial impacts from very energetic flaring could be high. Watch for future alerts and possible warnings. ** End of Alert ** ------------------------------ Date: 18 Mar 91 00:32:35 GMT From: munnari.oz.au!mullian.ee.mu.OZ.AU!strick@THEORY.TN.CORNELL.EDU Subject: Morse To: info-hams@ucsd.edu I have just become interested in amateur radio.
