A series of solar flares starting Wednesday and lasting into at least Friday were similar in strength to ones that in the past caused radio blackouts at the north and south poles and caused problems with GPS satellites and power grids, according to NASA.
The strongest flare came early Friday morning, just after 4am, and was rated as an X1.7-solar event, according to NBC News. The flare erupted from a newly discovered sunspot cluster, Region 1882, and caused a momentary radio blackout, officials said.

Scientists have three classifications for solar flares – C, M and X – with C being the weakest. X-level solar flares aimed directly at Earth have in the past wreaked havoc with satellite communications and GPS, as well as put orbiting astronauts in danger.
Stronger X-level eruptions fired squarely at our planet have been known to cause problems with power grids as well. This latest flare does not appear to have been aimed directly at Earth, officials told NBC News.
Scientists are also awaiting the results of geothermal imaging to determine if the flare was linked to a massive super-hot plasma explosion that hurled solar material into space at speeds upwards of 1million mph, according to NBC News.
Flares occurring earlier in the week peaked at M9.4 on Wednesday, with less M-class flares following the peak flare, according to NASA. Wednesday’s peak flare was linked to a massive plasma explosion, also known as a coronal mass ejection.
