Space Weather Instruments GOES-R Series

Solar imaging Space weather monitoring Geomagnetic storm warnings Space weather Benefits The changing Extreme Ultraviolet Solar eruptions can cause geomagnetic and environmental and X-ray Irradiance solar radiation storms, which can disrupt Sensor (EXIS) conditions from the power utilities and communication and sun’s atmosphere are Space Environment navigation systems, damage satellite known as space weather. In-Situ Suite (SEISS) electrical systems, and cause radiation Space weather Solar Ultraviolet damage to orbiting satellites, high- is caused by Imager (SUVI) latitude aircraft, and the International electromagnetic Magnetometer Space Station. SUVI and EXIS provide radiation and charged particles improved imaging of the sun and being released from solar storms. detection of solar eruptions, while SEISS and MAG Changes in the magnetic field and a more accurately monitor, respectively, energetic particles continuous flow of solar particles during a and the magnetic field variations that are associated powerful storm headed to Earth can disrupt with space weather. Together, observations from these communications, navigation and power grids as instruments enable NOAA’s Space Weather Prediction well as result in spacecraft damage and exposure to Center to significantly improve space weather forecasts dangerous radiation. and provide early warning of possible impacts to Earth’s space Monitoring solar activity and space weather environment The GOES-R Series hosts a suite of instruments that and potentially provide significantly improved detection of approaching disruptive space weather hazards. Two sun-pointing instruments events on measure solar ultraviolet light and X-rays. The Solar the ground. Ultraviolet Imager (SUVI) observes and characterizes complex active regions of the sun, solar flares, and eruptions of solar filaments which may give rise to coronal mass ejections. The Extreme Ultraviolet and X-ray Irradiance Sensors (EXIS) detects solar flares and monitors solar irradiance that impacts the Astronauts working outside the International upper atmosphere. Space Station are especially vulnerable to radiation from solar storms. The satellites also carry two instruments that measure their space environment. The Space Environment In-Situ √ Improved detection of coronal holes, solar flares, Suite (SEISS) monitors proton, electron and heavy ion and coronal mass ejection source regions fluxes in the magnetosphere. The Magnetometer (MAG) √ More accurate monitoring of energetic particles measures the magnetic field in the outer portion of responsible for radiation hazards the magnetosphere. √ Improved power blackout forecasts MPS-LO MPS-HI SGPS √ Increased warning of communications and navigation disruptions
