6pm Nov. 12, 2025 **JUST IN: The NOAA Space Weather Team has EXPANDED their "G4 storm watch" for this Wednesday evening into the wee hours of Thursady morning 11/12 and 11/13 in US eastern time. The aurora will interact with the nitrogen and oxygen molecules high in the atmosphere to cause the aurora. Northern Hemisphere is *currently* in G3 levels. Differences tonight compared to last night? Magenetic levels were 8 last night and tonight they're 5. That's lower. However, the solar winds are muc

Our first experiment with a video explanation of the activity was well received, so here is an update as we continue into the overnight to morning hours. We will attempt another update later on Wednesday if warranted. Stay informed at http://spaceweather.gov | NOAA NWS Space Weather Prediction Center

Launch countdown is on: Sentinel-6B is a new Earth-observing satellite that will measure sea levels for nearly all of Earth’s ocean, helping improve weather forecasting and protect coastal communities. Its data will continue a record we’ve been building since 1992. The Copernicus EU Sentinel-6/Jason-CS mission is an international collaboration with our partners: National Oceanic and Atmospheric Administration (NOAA) , ESA - European Space Agency , EUMETSAT , and CNES . It is slated to launch Nov
