Propagation News – 19 April 2020
Last week we said that we expected the Kp index to rise over the weekend due to incoming solar particles from an Earth-facing coronal hole. But we did warn that it was impossible to tell how severe it might be. In the end it didn’t amount to much, as although the stream was travelling at […]

Sunspot group 2759, as reported last week, never really amounted to much and vanished before it got to the solar disk’s edge. The matter from a solar coronal hole did hit the Earth last weekend as we predicted, sending the Kp index to four in the early hours of Saturday morning. Even though we don’t […]
Propagation News – 5 April 2020
The high speed stream of solar particles from a coronal hole on the Sun last week wasn’t moving as fast as we initially thought. As a result, its impact on Earth, and the subsequent rise in the Kp index to four, happened in the early hours of Tuesday morning and not the weekend as we […]

With the solar flux index remaining at 70-71 all week, conditions were pretty predictable. The Kp index rose to two or three at times, but on the whole geomagnetic conditions were stable. There was a large coronal mass ejection off the Sun on 20 March, but it wasn’t Earth-directed and didn’t affect us. It is […]
Propagation News – 22 March 2020
Last week saw a continuation of the zero sunspot regime we’ve been seeing for the past few months. The solar flux index remained in the range 70-72, with settled geomagnetic conditions and with the Kp index remaining in the range of one to two. Thursday the 19th was the exception, when the Kp index rose […]
Propagation News – 15 March 2020
A new sunspot group, numbered AR 2758 and from upcoming Solar Cycle 25, appeared this week. The region was located in the Sun’s southeast quadrant, but had faded away by Thursday the 12th. This was the first numbered sunspot region to appear in over a month as solar activity continues on at very low levels. […]
