Northern lights could get a boost from the spring equinox this weekend — here's why

A series of solar eruptions and fast solar wind streams could stir Earth's magnetic field this weekend, boosting aurora activity.
NOAA issued a moderate (G2) geomagnetic storm watch through March 21, with potential brief strong (G3) levels.
The spring equinox can amplify aurora displays by aligning Earth's magnetic field with solar wind.
The Russell-McPherron effect explains heightened geomagnetic activity around equinoxes.
Auroras could spread farther south than usual, offering mid-latitude skywatchers a chance to see lights.
Visibility will depend on solar wind direction; southward fields favor energy transfer into Earth's magnetosphere.
Forecasts are uncertain and auroras can be fickle despite favorable conditions.
Observers are advised to prepare cameras and aurora alerts for best viewing chances.
The event involves multiple CMEs and high-speed solar wind likely to interact with Earth's field.
