twyzheDUOK- NOAA Satellites July 22, 2022 Watch the arrow to spot the eruption! says a G2 (moderate) geomagnetic storm is likely July 23, bringing aurora to higher latitudes. Rachmeler explains that the video shows a prominence or filaments erupting in the lower right corner of the sun.įor #FullDiskFriday, we're checking out the sun! 🌞😎 #GOES16's Solar Ultraviolet Imager ( #SUVI) saw a #CoronalMassEjection on July 21. “That’s what we solar physicists call cool,” Rachmeler said. As testing and calibration wrap up on the newest satellite, there will soon be three eyes in the sky observing the sun continuously. The orange-red image (bottom right) is the 304 Angstroms wavelength measuring cooler plasma at 50,000 degrees Kelvin in the chromosphere, the layer below the corona. NOAA recently released the image above showing the differences between all six channels. While forecasters work to share weather data with the public, the NCEI makes sure the quality of the data is up to par.Īs testing and calibration wrap up on the newest satellite, there will soon be three eyes in the sky observing the sun continuously.īecause the sun is so hot, images of the sun are taken in ultraviolet wavelengths.Įach SUVI channel is a different wavelength of ultraviolet light, which samples plasma to varying temperatures in the outer atmosphere of the sun, known as the corona. She and her team work on calibration and validation of space weather instruments, like SUVI. Laurel Rachmeler is the head of the Solar & Terrestrial Physics section of NOAA’s National Centers for Environmental Information. It’s in the final phases of commissioning its powerful weather-observing instruments, including the Solar Ultraviolet Imager (SUVI), which helps forecast space weather.Ī version of SUVI has flown on all newer GOES satellites and can send back images to Earth within minutes to forecasters with NOAA’s Space Weather Prediction Center.ĭr. GOES-18 launched from Florida in March 2021 and is the third NOAA’s GOES-R geostationary satellite series.

NOAA is releasing stunning images of the sun taken by its newest weather satellite showing swirling plasma ejecting from the solar atmosphere into space and getting sucked back into the sun.
