The Sun emitted a strong solar flare on Jan. 5, 2023, peaking at 7:57 p.m. ET. NASA’s Solar Dynamics Observatory captured an image of the event, which was classified as X-class. bit.ly/3IsPJsW 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 space weath

2023 ended with flare! A strong solar flare – X5.0 – erupted from the Sun just hours before the clock struck midnight on Dec. 31 in North America, dethroning Dec. 14’s X2.8 solar flare as the largest of the year and of Solar Cycle 25. Learn more: https://go.nasa.gov/41EqcER | NASA Space Alerts

Massive X-Class Solar Flare Heading for Earth 🌎⚡ Auroras Incoming!” A powerful X-class solar flare has erupted from the Sun, launching a coronal mass ejection (CME) directly toward Earth. This event could produce bright, widespread auroras far beyond the polar regions, lighting up the night sky in vivid shades of green, pink, and purple. Space agencies are monitoring the solar storm closely, as strong CMEs can affect satellites, communications, and power grids. For sky watchers, this is a rare
