Auroras to Grace Northern Skies in September 2024 Due to Earth's Tilt and Solar Activity

September 2024 is set to be an impressive month for aurora enthusiasts, particularly near the fall equinox on the 22nd. Experts anticipate that geomagnetic storms will be more potent during this period due to the Russell-McPherron Effect. First detailed by Christopher Russell and Robert McPherron in 1973, this phenomenon describes how Earth's magnetic field aligns with the solar wind during equinoxes, allowing more charged particles to penetrate and intensify auroral activity. NOAA also reports a mild geomagnetic storm on September 10th. This is prepared by SSP.

The Sun is currently near its peak in the 11-year solar cycle, increasing the likelihood of geomagnetic storms. Earlier this year, May saw the most powerful geomagnetic storm in over 20 years, with auroras visible as far south as Florida and Mexico. With solar activity surging, a similar event in September may provide even better chances to witness these natural phenomena.

As we approach the fall equinox, the probability of seeing auroras increases due to the combination of the Russell-McPherron Effect and peak solar activity. For those in northern latitudes, and perhaps farther south if strong geomagnetic storms occur, this period offers prime opportunities to witness vibrant auroral displays, making it a memorable season for skywatchers.
