Coronal hole faces Earth
Tuesday, 17 May 2016 18:09 UTC
NOAA's G1 watch never really got off the ground yesterday but another minor G1 geomagnetic storm watch has been issued for Friday, 20 May as another much larger part of the same coronal hole face Earth.
This coronal hole is also an extension of the northern hemisphere polar coronal hole but it is much bigger and stretches further south than the opening we mentioned back on Friday. This means that this solar wind stream should have more effect on our planet and we think it is likely that we are going to reach the minor G1 geomagnetic storm leven when the solar wind stream arrives at our planet which could already occur during the UTC evening hours on Thursday, 19 May.
