The solar flux index stayed around the 70 mark last week, although a new tiny sunspot did become visible on Tuesday. Unfortunately this had little real effect on the SFI, although it did push the sunspot number to 11. This can be misleading due to the way sunspot numbers are calculated. You score 10 for […]

As predicted, the geomagnetic K-index hit five last week, although it wasn’t until early morning on the 26th. Conditions then settled as the week progressed. The US Space Weather Prediction Center has the K-index remaining low for the week commencing Sunday, 1 July, so make the most of the settled geomagnetic conditions. Due to a […]
