Magnetic Storm Forecast for the Weekend of September 19–20
Over the next two days, September 19 and 20, mild magnetic storms are expected. They will have a negligible effect on atmospheric pressure, so most people will not experience headaches, fatigue, or stress as a result.
On Saturday, September 19, solar activity with a K-index of 2.4 (green level) is expected, which corresponds to weak magnetic storms.
On Sunday, September 20, solar activity with a K-index of 2 (green level) is expected, corresponding to weak magnetic storms.
Geomagnetic activity is measured on a scale from 0 to 9. The planetary K-index is used for classification; a reading of 5 or higher indicates a strong magnetic storm.
This data comes from NOAA’s Space Weather Prediction Center (SWPC).
As a reminder, according to the lunar calendar, September 2026 is expected to bring both favorable days for various activities and days when it is better to be cautious and careful.
In September 2026, we enter the most favorable astrological period of fall—Mercury, the planet of communication, intellect, and technology, moves at maximum speed in its direct direction, unburdened by any shadow phases.
September is the time when the initial momentum of summer gives way to the measured pace of fall. The ability to translate accumulated experience into real, sustainable structures comes to the forefront, according to the retrograde planetary calendar.
