BOULDER, Colo. — The National Oceanic and Atmospheric Administration (NOAA) issued a minor solar radiation storm warning on Thursday morning following readings from a weather satellite in orbit around the Earth.
The warning is expected to last from 12:30 a.m. to 1 p.m. EST, Thursday afternoon.
Officials said that the warning is the result of a coronal mass ejection from the sun that happened around 10:19 p.m. EST on Wednesday as noted by radio signatures.
The energetic protons were expected to reach earth within 30 minutes to just a few hours.
Results from the event may include minor impacts on high frequency radio in the polar regions. However no biological or satellite issues are expected as a result of the storm based on the NOAA solar storm scales.
The storm is classified as S1 which, according to NASA, places it on the lower end of the solar storm spectrum – the most powerful ranking as an S5.
