Solar and Geomagnetic Activity Forecast – August 20, 2024

Solar activity is forecasted to be at moderate levels throughout the outlook period due to multiple complex regions visible on the sun’s disk and some regions expected to return from the sun’s farside, according to NOAA. There is a slight chance for R3 (Strong) radio blackouts over the next week because of monitored active regions on the sun’s nearside. However, proton events in geosynchronous orbit are not anticipated.

During this period, electron flux levels exceeding 2 MeV at geosynchronous orbit are predicted to range from normal to moderate. The geomagnetic field activity is mostly expected to remain quiet, with possible unsettled conditions on August 22-23 due to coronal hole effects. Long-term forecasts primarily contain recurring solar wind features like coronal hole high-speed streams (CH HSSs) and sector boundary crossings (SSBCs). Coronal mass ejections (CMEs) will be added as they occur.

On August 20, 2024, a K-index of 2 suggests a calm state of Earth’s magnetic field, indicating low geomagnetic disturbances and stable atmospheric conditions. This quiet period can be beneficial to individuals sensitive to geomagnetic changes, such as those with specific medical conditions, resulting in reduced headaches, fatigue, and mood fluctuations. Thus, the calm geomagnetic condition aids in promoting well-being and better overall functionality, providing a favorable environment for those attuned to atmospheric shifts.
