A geomagnetic storm watch will be in place until the end of the week due to the sun possibly affecting the weather.

A recurrent coronal hole high-speed stream from sun is expected to connect with Earth on Wednesday, when a solar wind field is expected to create minor geomagnetic storm conditions, according to NOAA.

"Geomagnetic responses are likely to escalate to G3 (Strong) conditions on 18 Aug due to the arrival at or near Earth of multiple 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."

A geomagnetic storm is defined as a major disturbance that results from "variations in the solar wind that produces major changes in the currents, plasmas, and fields in Earth’s magnetosphere.

NOAA will have a satellite to detect when a CME is approaching Earth, allowing forecasters at the Space Weather Prediction Center to give warnings to the public should the situation call for it.

The satellite, called DSCOVR maintains the nation's real-time solar wind monitoring capabilities according to the National Environmental Satellite Data and Information Service.
