Flightdiary.what a useful site.

Want to keep records on where you’ve flown and who you’ve flown with?  Keep it all there, brings out the anorak in all of us (especially me )

Rain? What’s that?

I come from a part of the UK that is currently VERY dry. Since April, we’ve had about 6mm of rain, during that time we would normally have had 60mm of rain, so the ground is dry, plants are staring to suffer, and, in the sky we see lots of cloud, but nothing falling from them.

Many places had storms just 2 weeks ago, we didn’t, and according to the excellent Netweather, we are unlikely to get huge amounts over the coming week, although, if we are really lucky we may get some heavy showers Thursday and Friday, I will keep you informed.

the Fax chart for Friday currently looks like this

Friday (I Hope)

Which gives me some hope at least

We shall see

Sunspots, Up, then Down, where next

Around February of this year (2011) it finally looked as though the current Sunspot Cycle was taking off, with multiple complex sunspots producing Coronal Mass Ejections (CME) and the sun looking fairly peppered with spots. Four months later, we’ve had a relapse, going by the Laymans Sunspot Count we are falling back into the trough of a quiet sun.

The Quiet Sun

Of particular concern to Radio Amateurs like myself is the fall off in the 10.7 flux associated with sunspots, throughout the last couple of months, it got over 100, now, it’s back in the mid 80’s, a level normally associated with a Solar Minimum, not half way up the ramp to a maximum. So what maximum should we expect? The NASA scientists, led by Hathaway have consistently revised downwards the expected maximum, now it’s around 50, and that’s in 2 years time.

Also the majority of spots seem to be Unipolar, as distinct from complex spots more likely to create CME’s.  As you can see above, just a single spot rotating over the face at the moment

Perhaps someone should tell the sun
