Re: [time-nuts] Solar flare alert...not quite
It's not actually a flare.that has been and gobe it a great bif glob of plasma, ejected by the same region. Spaceweather.com has a reputation for over-hyping these CME events. I could cause problems but there are a lot of conditions to be met before it is a disaster.

Re: [time-nuts] Solar flare alert
Joe, Cellphone frequencies are little affected by ionospheric effects, so I would be surprised if that was an effect though GPS is a different matter, or sat-phone.

Looks like this flare was a non-event: http://www.jackson-labs.com/images/gpsstat.htm On Jul 14, 2012, at 7:49, Alan Melia alan.me...@btinternet.com wrote: It's not actually a flare.that has been and gobe it a great bif glob of plasma, ejected by the same region.

Re: [time-nuts] Solar flare alert
Perhaps some of the cellular bands aren't affected, perhaps some are. I don't know the specific cause of yesterday's loss.. GPS uses around 1200/1500 MHz. The phone in question uses 850/1900 Mhz bands, so I think we're in the neighborhood.

Terrestrial cellphone signals do not pass through the ionosphere, so flares don't necessarily change things. There is anecdotal evidence, though, that solar activity can change the environmental RF background noise level, and that could have an effect on cellphone link margins. ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

Re: [time-nuts] Solar flare alert
Hi: Where is LORAN when you need it? I realize that if the flare is big enough LORAN would also have problems. Wouldn't it be nice if decision makers were required to be engineers?
