The Earth is set to fully exit the influence of a large coronal hole on the Sun by the end of Thursday, paving the way for a period of calm solar activity. This information comes from the Laboratory of Solar Astronomy at the Space Research Institute (IKI) of the Russian Academy of Sciences.

Earlier this week, on Monday, the laboratory reported the onset of the most intense geomagnetic storm in three months, triggered by the effects of this coronal hole.

According to current calculations, Thursday marks the final day the planet will be immersed in the disturbed plasma stream emanating from the coronal hole. Scientists have already observed a rapid decrease in the speed of interplanetary gas, with its temperature and density returning to average levels.

Following the initial impact on September 15, which saw strong G3-level geomagnetic storms, the magnetic field has since stabilized. From September 16 to 18 (Tuesday to Thursday), no new significant events occurred, and geomagnetic indices remained within the «green zone» (indicating stable conditions). While a slight chance of minor disturbances remains for today, all associated risks are expected to be completely gone starting tomorrow.

The current solar flare activity is considered moderately calm. The Sun is producing weak plasma ejections, but their power is minimal, and models indicate they are propagating away from Earth. The overall forecast for the coming days remains peaceful.
