This arrived today. Published in 1984. As a teenager I wanted to be #RogerDean - I fell in love with his work after I bought the album “Relayer” by Yes. Changed my life. Although my dreams of being a professional artist never materialised. #NoRegrets #MagneticStorm

Strong aurora activity at both poles🌌🌍 .
At the same time, major radio propagation disruption with this magnetic storm with coefficient A=73 and K=7⚡

The solar cycle, geology, and geoelectric hazards for power grids

When sunspots are large and numerous, intense magnetic storms are likely to occur on the Earth. Magnetic storms can generate electric fields in the Earth, and these fields can, in turn, interfere with electric power transmission grids that are grounded at the Earth’s surface. Across the contiguous United States, geoelectric hazards are highest in the Upper Midwest and in the East. These regions correspond to geological structures that are electrically resistive, and they have, historically, experienced the most interference to electric power systems....
