BIG SUNSPOT: The sudden emergence of big sunspot 1045 over the weekend
has caused a sharp uptick in solar activity. The active region has
produced three M-class and almost a dozen C-class solar flares since it
appeared on Saturday. The strongest blast, an M6-class eruption on Feb.
7th, may have hurled a coronal mass ejection toward Earth. High-latitude
sky watchers should be alert for auroras in the nights ahead as a result
of this activity. Also, ham radio operators are picking up strong solar
radio bursts using shortwave receivers. Sample sounds and images may be
found at http://spaceweather.com.

The sun has been ticking up for a while now.

Never seen a configuration of spots like that before.

Sunspots *cause* solar activity?

Sam has issues with cause and effect.

I've just read that the GPS system is likely to go haywire as solar
activity increases.

You mean like it did during the last sunspot cycle? Oops.

This may well be true but GPs wasn't in every car, lorry, boat, phone
and camera like it is now.

Europe has screwed up its own promised GPS with endless, expensive
delays and bickering.

Fine, believe what you want to. IMO journalists who sensationalize things
in order to sell advertising should be shot on sight.

Which has a great deal to do with European politics and nothing at all to do
with sunspots.

Fearmongering. Read it through and you find that nothing much is going to
happen--maybe there will be outages for a few minutes a few times a year.
The rest is describing the normal operation of the system but he words it as
if it's dangerously degraded.

Sun induced geomagnetic storms can render some GPS based
survey equipment useless to to interference from ionospheric
currents at some latitudes. The was noted during the last
solar max.

Most GPS hobbyists wouldn't notice much.
