Solar storm forecast: Weak power grid fluctuation possible as particles from Sun hit Earth

According to the SWPC, the second CME overtook the first one and may arrive by Wednesday.

The SWPC’s 24-hour summary reads: “Solar activity was very low and the solar disk was spotless.

“The CMEs that left the Sun on January 1 and 2 were analysed and modelled.

“The first, slow-moving CME was overtaken by the faster second CME on January 2.

“Model runs suggest arrival on January 6; however, confidence is somewhat low in timing due to the anticipated interactions between the two CMEs coupled with a weak coronal hole (CH) high-speed solar wind stream (HSS) due to the arrive late on January 5.”
