A geomagnetic K-index of 5 is expected, indicating a minor geomagnetic storm. This is exciting news for sky-watchers, as it may lead to visible aurora displays at lower latitudes. Sky-watchers at higher latitudes, particularly those above 60 degrees Geomagnetic Latitude, may want to look out for aurora activity during this time.
