Short summary
In this work, we simulated the effect of atmospheric drag on satellites in low Earth orbit (LEO) during 1-month intervals of disturbed and quiet solar geomagnetic activity. Our results show that geomagnetic storms (e.g. the Bastille Day event) can cause a significant drop in LEO satellite altitudes and increase their background orbit decay rate by 50–70 %. This work can contribute to improved situational awareness and mitigation of potential threats solar energetic events pose to satellites.
