By the end of Thursday, planet Earth is projected to fully emerge from the direct influence of a substantial coronal hole present on the Sun. This transition is expected to lead to a period of calm solar flare activity in the upcoming days. This significant update was provided by specialists at the Laboratory of Solar Astronomy, part of the Space Research Institute (IKI) of the Russian Academy of Sciences.
Just last Monday, experts from the same laboratory reported the onset of the most intense geomagnetic storm witnessed in the past three months, which was directly attributed to the impact of this coronal hole. According to the latest calculations, today marks the final day that Earth will be situated within the stream of turbulent plasma originating from the solar coronal hole. Observational data currently indicates a rapid decrease in the velocity of interplanetary gas, alongside a noticeable return of its temperature and density to their typical, average levels.
Following the initial powerful G3-level geomagnetic surge recorded on September 15, Earth`s magnetic field successfully stabilized. From September 16 through September 18 (Tuesday to Thursday), no new significant space weather events were observed. Although geomagnetic indices experienced an elevation, they consistently remained within the safe “green zone.” While a minor possibility of weak disturbances still exists today, scientists assure that all associated risks will be entirely mitigated starting from tomorrow.
Currently, the overall solar flare activity is categorized as moderately calm. The Sun continues to emit minor ejections of plasma, but their power is extremely low, and these emissions are largely observed to travel away from our planet, as evidenced by appended models. The comprehensive forecast for the forthcoming days suggests a continued period of tranquil space weather conditions.
