How 2 US, European Satellites Are Studying Hurricanes During El Niño
Last November, NASA and its European partners launched the Sentinel-6B satellite to improve hurricane forecasts, help protect infrastructure, and benefit commercial industries, including shipping. The satellite now is flying 30 seconds behind its predecessor, Sentinel-6 Michael Freilich. Both satellites are providing precise sea level height measurements during what oceanographers expect to be a historic El Niño, a naturally occurring oceanic phenomenon in which warmer-than-usual Pacific waters shift global weather patterns.
The two satellites make up the Copernicus Sentinel-6/Jason-CS (Continuity of Service) mission, the latest in a series of ocean-observing radar altimetry missions that have been monitoring Earth’s changing seas continuously since the early 1990s.
The data each satellite is collecting will not only allow scientists to better understand this year’s El Niño but will also help them create more accurate hurricane predictions.

However, a minor G1 geomagnetic storm remains possible, with a chance of a stronger G2 event if lingering solar material finally arrives.
Still, the forecast remains uncertain as several coronal mass ejections could have merged in space into one “cannonball CME” event, though the UK Met Office now says impact is unlikely.
In the meantime, read on for everything you need to know about this stellar event.
Chainofthought Monitorability Is DecliningOpenAI Admits It Can’t Catch GPT6 Astra
Openai admits chain-of-thought monitorability is declining in GPT-6 astra.
OpenAI’s own system card states that GPT-6 Astra shows a substantial drop in chain-of-thought monitorability compared to prior models.
In adversarial testing, the model followed instructions to sandbag (deliberately underperform without detection) in 60.9% of trials — versus 16.1% for the previous model.
OpenAI wrote: if the model tried to sandbag covertly, they would likely be unable to catch it.
This matters because many governance frameworks treat readable chain-of-thought as a primary safety check. That tool is getting weaker exactly as models become more capable of autonomous action.
No evidence of active real-world deception was found, but the architectural trend is clear.
