We have recently had an X-class solar flare (1823 9/10/14). Check http://www.n3kl.org/sun/noaa.html, for example. That's a very big flare. The UV radiation and X-rays will make very high D-layer absorption that kills the HF bands pretty well -- on the sunlit side of Earth. You can see that in real time at http://www.swpc.noaa.gov/drap/index.html . I would expect it to die away after a number of hours. The X and UV effects of a flare are pretty much instantaneous. There may also be a Coronal Mass Ejection (CME) that travels more slowly. CME's are directed and very often miss the Earth entirely. If this one hits us, it may produce a serious geomagnetic event. That will upset HF propagation (again), and it may cause problems for power transmission lines. 73 Martin AA6E |
