A thin east-west aligned northern hemisphere coronal hole is facing our planet today.
A solar wind stream from this coronal hole is expected to arrive on Wednesday, 14 March. Active geomagnetic conditions (Kp4) are likely with a minor chance that we are going to get minor G1 geomagnetic storm conditions which is a Kp of 5. We are now near the spring equinox which means its slightly easier for geomagnetic disturbances to develop hence the possible G1 watch.
Like with any coronal hole solar wind stream, the strongest effects are likely to occur when the Co-rotating Interaction Region (CIR) ahead of the solar wind stream itself arrives which will likely be on Wednesday. The solar wind stream itself which is the fast but not very dense solar wind could persist for days considering the shape of this coronal hole. For more information about coronal holes we invite you to read our help article about this subject.
