NASA released this Wednesday (21) a video recording the .
The Solar Dynamics Observatory record shows a bright flare near the center-left of the Sun. The record captures a narrow band of extreme ultraviolet light that highlights the extremely hot material in solar flares. This image is colored in teal.
In the second part of the video, the eruption is shown simultaneously in three wavelengths.
The solar flare was classified as an X1.9 flare. Class X indicates the most intense eruptions, while the number provides more information about their strength.
According to information from NOAA’s Space Weather Prediction Center (SWPC), a grade 4 (severe) geomagnetic storm warning – the scale goes up to 5 – was issued.
“A category S4 severe solar radiation storm is underway – this is the largest solar radiation storm in over 20 years,” shared SWPC on X, formerly known as Twitter. “The last time S4 levels were observed was in October 2003. Potential effects were primarily limited to space launches, aviation and satellite operations.”
