Sometimes space weather can be just as noteworthy as weather on Earth. There was an X1 solar flare on October 28, 2021, at 10:35AM CDT (15:35Z) detected by the GOES Solar Ultraviolet Imager (SUVI). The GOES-16 and 17 satellites each house the SUVI, which is an extreme ultraviolet telescope that detects photons that are not detectable from the Earth’s surface.<\/p>\n\n\n\n

This type of X1 solar flare event can<\/em> affect Earth’s conditions. Today’s solar flare is associated with a “strong” R3 radio blackout in which high frequency radio communication can be impaired. The NOAA Space Weather Prediction Center (SWPC) is responsible for observing and forecasting flares. More information is available here<\/a>.<\/p>\n\n\n\n

This SWPC site<\/a> shows solar animations at various wavelengths and updates in real-time.<\/p>\n\n\n\n

NOAA SWPC is also in charge of monitoring and forecasting aurora (the northern lights, aurora borealis, or southern lights, aurora australis). Aurora occur as a result of solar flare activity that releases energy into Earth’s magnetic field. NOAA Space Weather has issued a “G3” geomagnetic storm watch, predicting aurora visible as far south as Pennsylvania, Iowa, and Oregon through this Saturday October 30. More information on aurora and aurora forecasts can be found here<\/a>.<\/p>\n\n\n\n

To visualize different characteristics of the sun, CIMSS scientists have built a webapp tool called an “RGB maker” for SUVI data in which data at three different wavelengths are combined to create an image. You can find the tool here<\/a>. (Note for users: select your red, green, and blue wavelengths and then combine channels. General users can ignore adjusting the scale and gamma factors.)<\/p>\n\n\n\n

The SUVI RBG maker functions similarly to how traditional Red Green Blue satellite composites are created, only it combines from the six SUVI bands. Those band wavelengths are: 94 \u00c5, 131 \u00c5, 171 \u00c5, 195 \u00c5, 284 \u00c5, and 304 \u00c5. [One \u00c5 (pronounced Angstrom<\/em>) is equal to 0.0001 microns or 1e-10 meters.] The table below lists the type of solar phenomena that are observable with each band.<\/p>\n\n\n

Six wavelength bands detect solar phenomenon on SUVI. Space weather forecasters use this data to observe solar flares and monitor Coronal Mass Ejections (CMEs), for example. <\/figcaption><\/figure>\n<\/div>\n\n\n
