Hi Everybody;
NOAA issued a ALTTP2 alert. This is not the kind of alert I would expect at solar minimum. I also honestly have to admit this is the first time I see it. It states that we will be getting nit by a plasma cloud at the speed of almost 900km/s. This is fast! The only indication that there was a masse ejection is a B class solar x-ray-flux spike. Kp and proton flux are low too. Conditions at the MDSR test station are still reasonable good, but if the type II emission hits we will get some serious propagation change. We cannot predict if this will be good or bad for
Stay tuned!
Current conditions at the MDSR test station: 80m open S5 40m open S4 30m open S3 20m open S4 15m closed S3 10m closed S1
