But thus far, in the highly-orange-light-polluted Chicago skies, the aurorae have been essentially invisible. Out in the northern wilds, toward Wisconsin (an hour's trek from here), I am reliably informed, in those darkened skies though. . . its been quite the show. This, via NASA's SDO blog:
. . .Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.
This flare is classified as an X3.9 flare. X-class denotes the most intense flares, while the number provides more information about its strength.
To see how such space weather may affect Earth, please visit NOAA’s Space Weather Prediction Center https://spaceweather.gov/, the U.S. government’s official source for space weather forecasts, watches, warnings, and alerts. NASA works as a research arm of the nation’s space weather effort. . . .
Now you know -- smiling. May just drive on northward, tonight -- for grins.
