Geomagnetic and Solar Activity Observation and Forecast for August 27

Within the last 24 hours, the most significant 3-hourly Kp index recorded was 3, which is below NOAA Scale levels. For the period between August 26 and August 28, 2024, the highest projected 3-hourly Kp index is 4, which also remains below NOAA Scale thresholds. No minor or greater geomagnetic storms are expected during this period, and no considerable transient or recurrent solar wind features are anticipated.

On August 27, 2024, the K-index represents a geomagnetic activity level of 3, classified as "quiet," NOAA reported. This low activity reflects minimal disturbances in the Earth's magnetic field, typically due to stable solar wind conditions and a calm magnetosphere. Generally, this level has no substantial impact on daily life for the majority of people. However, individuals sensitive to geomagnetic changes, such as those with specific health conditions, might experience mild symptoms like headaches, fatigue, or disrupted sleep patterns. These individuals are advised to maintain practices such as staying hydrated, managing stress, and ensuring adequate rest to alleviate any potential discomfort during these quiet geomagnetic periods.

In the last 24 hours, solar radiation monitored by NOAA GOES-18 stayed below S-scale storm levels, with no radio blackouts. Additionally, a slow-moving solar ejecta is forecasted to brush by Earth late on August 27 to early August 28.

Overall, the current and forecasted geomagnetic and solar radiation conditions suggest typical and non-disruptive levels of space weather activity.
