At the risk of sounding like a stuck record, the Sun remained spotless this past week with a solar flux index stuck firmly around the 70 mark. Geomagnetic conditions were mostly settled with a maximum planetary K-index of four, although on average it was usually much lower than this, around one or two. Many are […]

This week saw relatively-settled HF conditions after the effects of a geomagnetic storm that impacted Earth at the weekend had passed. The Kp index was mostly around one or two thanks to a reduced solar wind. A small solar coronal hole did become Earth-facing on Wednesday, the 9th, but its effects, if any, won’t be […]
