Fast Solar Wind Bookends an Earth-Directed Graze | Space Weather News 12.01.2021

This Space Weather News forecast sponsored in part by Millersville University:
This week we have a partly Earth-directed solar storm sandwiched between two pockets of fast solar wind! The storm on its way will graze us to the south by December 3rd. NASA and NOAA prediction models disagree as to exactly when, but we can expect impact to be sometime between mid-day on December 2 and late December 3. This wide window doesn’t really matter all that much considering this solar storm is already preceded by some minor storming due to the first pocket of fast wind that is hitting now and will be followed by more! This means storming could occur from now until week’s end, especially at high latitudes. We have already jumped to solar storm levels and seen some gorgeous aurora at high latitudes over the past 24 hours and could do so again. As for mid-latitudes, the chances for aurora over the next few days may be sporadic, but conditions will look more favorable as the solar storm arrives. In addition to this activity at Earth, we have had some new active regions emerge on the Sun, which is good news for amateur radio operators. We even have a small chance for an M-class flare, although the possibility is still pretty remote. We will be monitoring the growth of these regions over the next few days in case they turn out to be substantial, but for now, solar flux is hovering near the low 90s. This means marginal to good radio propagation on Earth’s dayside. As for GPS reception, there may be issues near dawn and dusk and near aurora over the course of this week, so stay vigilant if you drive, fly safe if you are a UAV pilot, and calibrate your magnetometers often!
