- A geomagnetic storm watch will be in place until the end of the week due to the sun possibly affecting the weather.
- “Geomagnetic responses are likely to escalate to G3 (Strong) conditions on 18 Aug due to the arrival at or near Earth of multiple coronal mass ejections (CMEs) that have departed the Sun since 14 Aug,” NOAA warned. “Despite the numerous CMEs, most are expected to have little to no impact at Earth, however, at least four have potential Earth-directed components.”
