☀️A new era in space weather forecasting is beginning... Last year, we saw an increase in solar storms that lit up the skies with stunning auroras across Europe. However, these events can be disruptive, effecting power, satellites & communications. Space weather needs to be predicted early and accurately to give us the crucial time needed to protect satellites, astronauts and vital infrastructure on Earth. That’s where our Vigil mission comes in. Acting as a dedicated ‘space weather reporter’, V

It’s #SunDay! This week’s space weather report includes: · 11 M-class flares · 0 C-class flares · 23 coronal mass ejections · 1 geomagnetic storm This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity. The highlight this week is a stunning M8.1-class flare and post-flare arcade beginning at about 0:26. See [the following post for a close-up GIF of the event. Post-flare arcades are the series of loops of solar plasma that form right after a flare as the region cools dow

NOAA’s Space Weather Prediction Center operates 24x7 to continually monitor and forecast space weather — issuing space weather watches, warnings, alerts, and forecasts.

The Sun emitted a strong solar flare on Nov. 30, 2025, peaking at 9:49 p.m. ET. NASA’s Solar Dynamics Observatory captured an image of the event, which was classified as X1.9 class: go.nasa.gov/4alXf6P Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground. However — when intense enough — they can disturb the atmosphere in the layer where GPS & communications signals travel. To see how such sp
