Coronal holes face Earth

Two coronal holes close to the solar equator are now facing Earth. These coronal holes are now sending their solar wind streams towards Earth which will likely cause enhanced geomagnetic conditions on 30 April, 2016.

These coronal holes aren't very large but they are located at a favourable latitude close to the solar equator. Active geomagnetic conditions (Kp4) are expected when the dense solar wind stream (co-rotating interaction region) just ahead of the high speed solar wind stream arrives at our planet, which should occur next Saturday.

Any mentioned solar flare in this article has a scaling factor applied by the Space Weather Prediction Center (SWPC), the reported solar flares are 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.
