Last but not least we have a list detailing all solar flares that took place today. All times listed are in UTC. The plot on this page shows us the most recent 24-hour solar X-ray data from the primary GOES satellite. You can zoom in on this plot by selecting ...

4 天之前 · Solar activity dropped to moderate, with multiple C-class flares and the strongest event an M3.0 flare from Region AR3981. The northeast cluster of sunspots continues to be the primary...

A lot of people come to SpaceWeatherLive to follow the Sun's activity or if there is aurora to be seen, but with more traffic comes higher server costs. Consider a donation if you enjoy SpaceWeatherLive so we can keep the website online! Get instant alerts!

2024年12月30日 · Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts. The first flare is classified as an X1.1 flare.

4 天之前 · Solar activity is expected to be moderate with a slight chance for an X-class flare on days one, two, and three (04 Feb, 05 Feb, 06 Feb).

3 天之前 · The GOES X-ray plots shown here are used to track solar activity and solar flares. Large solar X-ray flares can change the Earth’s ionosphere, which blocks high-frequency (HF) radio transmissions on the sunlit side of the Earth.

2024年10月9日 · Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts. This flare is classified as an X1.4 flare.

2019年12月24日 · NOAA’s GOES satellite time-lapse of Solar Cycle 25 from December 2019 through April 2023 alongside the progression of the number of sunspots. The Solar Ultraviolet Imagers (SUVI) create images of the solar corona at six different extreme ultraviolet wavelengths.

The daily Solar and Geophysical Activity Summary is a brief list of solar and geophysical events and indices for the previous UTC day, including energetic solar flares, proton events, geomagnetic activity, and stratospheric warming alerts.

2024年5月11日 · NASA’s Solar Dynamics Observatory captured this image of an X5.8 solar flare peaking at 9:23 pm EDT on May 10, 2024. The image shows a subset of extreme ultraviolet light that highlights the extremely hot material in flares created from a mixture of SDO’s AIA 193, 171 and 131 channels.
