The intensity of the storm shut down telegraph systems across Europe and North America and even set some buildings on fire when equipment started sparking.
Luckily for us, Saturday’s CME will not hit us head-on and its effects will be minor at most.
The SWPC said: “A G1 (Minor) geomagnetic storm watch is in effect for February 23 and 24, 2020, UTC-days.
“A CME that occurred on February 20, 2021, was analyzed and modelled, and it is likely that the flanking edge of the CME may arrive as a minor glancing blow late on the February 23 UTC-day.
“Any CME influences would likely continue into early on the February 24 UTC-day.”
