Resources to educate students, teachers, and the general public about meteorology, space science, earth-observing satellites, weather phenomena and benefits GOES-R will provide to society.
Information and resources to ensure that the user community is prepared for the new types of satellite imagery and data that will be available from the GOES-R satellite series.
Solar Ultraviolet Imager is a telescope that observes the Sun in the extreme ultraviolet (EUV) wavelength range. It provides full-disk solar images with approximately 5 arcsec spatial resolution at 10 second imaging cadence around the clock except for brief periods during eclipses. Six EUV bandpasses covering spectral lines of iron and He II cover the entire dynamic range of solar EUV features from coronal holes to X-class flares and enable the estimation of coronal plasma temperature and emission measure.
SUVI will observe and characterize complex active regions of the Sun, solar flares, and the eruptions of solar filaments which may give rise to coronal mass ejections. Depending on the size and the trajectory of solar eruptions, the possible effects to the Earth’s environment, referred to as space weather, include the disruption of power utilities, communication and navigation systems, and may cause damage to orbiting satellites and the Spacestation. SUVI observations of flares and solar eruptions will provide an early warning of possible impacts to the Earth environment and enable better forecasting of potentially disruptive events.
The SUVI is mounted on the spacecraft-provided Sun Pointing Platform (SPP) which is located on the solar array yoke. The spacecraft (observatory) points the SUVI to the Sun. The observatory provides power and data interfaces to the SUVI and transmits SUVI telemetry to the ground. Spacewire is the data interface format.
SUVI Operational Goals
1.
Locate coronal holes for geometric storm forecasts
2.
Detect and locate flares for forecasts of solar energetic particle events related to flares
3.
Monitor changes in the corona that indicate Coronal Mass Ejections (CMEs)
4.
Detect active regions beyond the east limb for activity forecasts
5.
Analyze active region complexity for flare forecasts
Six wavelength bands observe the range of solar
phenomena important for space weather forecasting
