Geomagnetic Activity Observation and Forecast for August 22
Over the past 24 hours, the highest 3-hr Kp index observed was 2, which is below the NOAA Scale levels. For the period from August 21-23, 2024, the highest expected 3-hr Kp index is 3.67, still below NOAA Scale levels. There is a slight possibility of an S1 (Minor) solar radiation event through August 23, primarily due to developments in Active Region AR3790.
There is a likelihood of R1-R2 (Minor to Moderate) radio blackouts due to M-class flare activity through August 23, alongside a slight chance for stronger R3 events, particularly from ARs 3790 and 3795.
On Thursday, August 22, 2024, a K-index level of 4 is predicted, signaling modest geomagnetic activity typically linked to minor disturbances in Earth's magnetic field. Though generally considered relatively quiet compared to higher readings, this level can impact sensitive individuals with health conditions like migraines or anxiety disorders. Potential effects include headaches, fatigue, and emotional sensitivity, which vary among people. While the overall impact is minimal, some may experience changes in sleep patterns or mood. Awareness and management of geomagnetic conditions can help mitigate discomfort, and self-care practices such as regular sleep schedules and stress reduction are recommended during these periods.
