Optical DX - NOT amateur radio

For years I have been fascinated by mirages and increases in refractive index at optical frequencies. What is often not realised is that how far we can see changes depending on the refractive index .This photo was a Facebook memory from some years ago.

Sunspots - Wednesday December 11th

 Solar flux is 172 and the SSN 125. A=8 and K=2.

Notre Dame, Paris - NOT amateur radio

This was badly damaged by fire 5 years ago (my half French grandchildren cried buckets) but has now been reborn . 

This is it now.

How ignorant we are - NOT amateur radio

 As part of my University of the Third Age course in Cambridge I was studying great physicists. The take-away remark is just how little we know! 

For centuries great minds have tried hard to better understand the universe at macro and micro level, without really understanding it.

Quantum mechanics was only put forward a little over one hundred years ago. All we really know is that everything is stranger than we ever imagined.

I don't think our human brains are capable of fully comprehending this.

Next term I am studying "Computers, the Brain and AI".  Perhaps AI could help?

The other course (totally different!) was about the Balkans.

6m QRP FT8 (Tuesday)

10m QRP WSPR (Tuesday)

My 500mW beacon was turned on at about 1005z.

UPDATE 1837z:   31 stations have spotted me. See table.

Sunspots - Tuesday December 10th

 Solar flux is 173 and the SSN 94. A=16 and K=2.

Rethatching - NOT amateur radio

In the nearby village of Lode there are many thatched cottages. One is having its thatched roof replaced, a job that takes many weeks. The one in the photo has been worked on for about 2 weeks already.

10m 500mW WSPR TX (Monday)

My beacon was turned on at breakfast time. At  0902z, several spots from the Canary Is..  It seems this (I assume) single hop F2 path is usually open.

UPDATE 2005z:  48 stations have spotted me today.

6m QRP FT8 (Monday)

 My gear was turned on just after 0800z. At 0858z already 20 stations have copied me including several in mainland Europe.

UPDATE 1957z:  71 stations spotted my 6m QRP  FT8.
