Additional Comments

The solar wind is still experiencing the waning influence of a coronal hole high-speed stream (HSS). Geomagnetic conditions are expected to remain at mostly QUIET levels through the first forecast interval, but there remains a slight chance for some isolated ACTIVE periods.
During the second forecast interval there is a possibility of a weak glancing blow from a CME that left the Sun on 25 Feb. There is also a chance for HSS effects from two small coronal holes late in the second forecast interval. Whilst geomagnetic activity is expected to remain at mostly QUIET levels there is a chance for some ACTIVE and possibly STORM G1 periods if the CME and HSS become geoeffective.
Time of forecast: 27 Feb 2026
