Geomagnetic and Solar Activity Report – October 3, 2024

On Thursday, October 3, 2024, geomagnetic activity is calm with a K-index of 2, indicating stable conditions in the Earth's magnetosphere, NOAA reported. This low level of geomagnetic activity generally minimizes disturbances caused by solar winds or coronal mass ejections. Consequently, there are few, if any, impacts on radio communications, satellite operations, and power systems. Health effects for weather-sensitive individuals are also minimal; those with cardiovascular conditions or migraines may find their symptoms less pronounced during such calm periods. While the link between geomagnetic conditions and health is still under investigation, many weather-sensitive individuals report feeling more at ease when geomagnetic activity is low.

In terms of solar radiation activity, no significant active region activity that could produce solar radiation storms is expected. Specifically, no S1 (Minor) or greater solar radiation storms are forecasted. However, minor to moderate radio blackouts (R1-R2) are likely, with a slight chance of more severe events (R3 or greater) occurring over the day.

Hence, overall, the conditions for October 3, 2024, exhibit a combination of low geomagnetic activity and moderate likelihood of minor radio disturbances, both favoring minimal adverse effects on communication systems and health sensitivities.
