. A solar storm in 1989 caused blackouts in parts of Canada, while in October 2003, a solar flare eruption expelled gigantic clouds of solar material The image shows a subset of extreme ultraviolet light that highlights the extremely hot material in flares and which is colorized in orange.
. One of the awaited coronal mass ejections ( CMEs ) arrived last night. December 2019 marks the beginning of Solar Cycle 25, and the Sun's activity will once again ramp up until solar maximum, predicted for 2025.
