What do A and K indices mean?

Most days I give the solar data. Several people wonder what the A and K indices mean.  Hopefully this ARRL file will explain.   

Basically a high solar flux is good for HF conditions and low A and K indices mean stable geomagnetic conditions, which are good. 

As a rough indicator look for a high solar flux and low A and K indices for good HF conditions.

BST and GMT

This weekend we return to GMT from daylight saving time (BST) in the UK. This means darker evenings and an earlier drawing of curtains. It's amazing how we adapt.  

Sunspots - Friday October 24th

 Solar flux is 134 and the SSN 92. A=10 and K=3.

10m 500mW WSPR

My beacon was turned on just before lunch.

UPDATE 1851z:  31 stations spotting me with the USA and Canada the furthermost. See map showing stations spotting me today. Now QRT.

6m 5W FT8 (Thursday)

My gear was turned on just before lunch.

UPDATE 1804z:   14 stations have spotted me including 1 in Sweden and 1 in Italy. See map. Now QRT on 6m.

DX Explorer

 This is a website I like. There are lots of videos with interesting projects such as this one.

Cambridge market

This is in the centre of Cambridge, UK.  It used to be bigger, but there are fewer occupied stalls these days. I guess the council charge them too much.

More fool them?

I read today that some people pay £750 just for breakfast. This is what some people have to live on for a whole month. Personally, I think this is obscene.

Thursday plans

 Later I hope to go on 6m 5W FT8 and 10m 500mW WSPR as long as the thunder stays away. It could come our way later.

Sunspots - Thursday October 23rd

 Solar flux is 133 and the SSN 117. A=4 and K=1.
