This is the best summary I could come up with:
Known as coronal mass ejections, or CMEs, these blasts could consolidate into a supersize CME capable of triggering a strong geomagnetic storm and aurora visible in the northern United States and Europe on Thursday or Friday.
It produced a pulse of extreme radiation that “blacked out shortwave radio communications across the South Pacific Ocean and parts of the Americas … for as much as an hour,” according to SpaceWeather.com.
Cannibal CMEs are relatively rare but are more common near the peak of the sun’s 11-year solar cycle, which NOAA expects to occur between January and October 2024.
A NASA space weather model estimates that the geomagnetic storm will strike Earth around midday Friday, but it could arrive as soon as Thursday.
“Late Thursday night currently has the best chance of aurora ... but forecasting these events [is] complicated, especially with three eruptions arriving within a relatively short window,” French said.
Earlier this month, a G3 geomagnetic storm produced vibrant colors visible to the naked eye near the U.S.-Canada border and appearing as a faint glow as far south as Texas and North Carolina.
