Solar Storm Forecast

“Space Weather may be quiet right now, but the Sun has some exciting news! Not only has it shot several mini-solar storms at Earth, but it has given us two new peeks at the coming solar cycle 25! A short-lived solar cycle 25 sunspot appeared momentarily back on November 9 and then another appeared on November 17 and started growing. Although this region might not last long, it is definitely visible as a plage region so get a look while you have the chance. Even if they are momentary, these back-to-back regions are the strongest sign yet that solar cycle 25 is coming! See the details of these two new cycle regions, learn about the short bursts of fast solar wind and mini-solar storms headed our way, and find out what else our Sun has in store for us this week.”
