GEOMAGNETIC ACTIVITY
July 26: Geomagnetic field activity was at quiet levels. Despite the quiet conditions, Earth remained within a recurrent coronal hole high-speed wind stream. Forecast: Geomagnetic field activity is expected to increase to quiet to active levels with a slight chance for a minor storm on July 27 as the current coronal hole high-speed stream intensifies. Activity is expected to decrease to quiet to unsettled levels on July 28-29 as the high-speed stream gradually subsides. Source: SEC/NOAA
