August saw a stark decrease in sunspots compared to July, yet this decline is not unusual as solar cycles can exhibit fluctuations even during the peak phase.
Yet, this month's solar activity set the stage for increased geomagnetic activity in early September, including a G3-level geomagnetic storm that resulted in stunning auroras across various regions, including the United States.
Considering the erratic solar activity and significant geomagnetic storms we can expect more extreme weather in the upcoming months.
Deadly floods and landslides continued to wreak havoc across the world multiple regions in August, together with unseasonal snow and massive hail made the headlines more than once.

A magnitude 6.1 earthquake struck Turkey's north-western province of Balikesir on Sunday, leaving widespread damage, with shocks that were felt some 200 kilometers (125 miles) to the north in Istanbul.
