There was a very good opening on 28 MHz on Sunday the 7th of October 2018. Using the FT8 mode, I heard 292 stations in 29 countries...
The signals around Europe were Sporadic-E. The opening to South Africa and South America were probably a mix of Sporadic-E and F2.
As soon as I saw all of those South American stations, I new that conditions were exceptional and was wondering if there might be an aurora later? Sure enough, there was an aurora later in the evening!
I've seen this before.....really good conditions on 10m followed by an aurora. So much for 10 metres being dead at the solar cycle minimum.
