The NOAA SWPC has issued a minor G1 geomagnetic storm watch for this Friday, 19 October.

A coronal hole located on the Sun's southern hemisphere is facing our planet today.

A large coronal hole is facing our planet today. This coronal hole seems to be an extension of the northern polar coronal hole that stretches southward all the way to the Sun's southern hemisphere.

Minor G1 geomagnetic storm conditions were observed earlier this night as a dense solar wind structure arrived at our planet. The north-south direction of the interplanetary magnetic field went mostly southward dipping as low as -9nT and that combined with the equinox effect caused us to reach minor G1 geomagnetic storm conditions at 02:45 UTC. Source is likely the southern extension of the polar coronal hole that you can see in this video from NASA/SDO.

The previous coronal hole solar wind stream gave us some great auroral displays around the world as it caused moderate G2 geomagnetic storm conditions on 11 September which was predicted perfectly by the NOAA SWPC. Today we have yet another coronal hole facing our planet which should be exciting news for aurora watchers at high latitude locations!

A high speed coronal hole solar wind stream arrived at our planet yesterday from a small equatorial coronal hole but it did not produce much geomagnetic activity here on our planet. While the solar wind speed increased to above 500km/s, the north-south direction of the IMF stayed mostly northward and little geomagnetic activity was observed. The Kp-index never increased above Kp2 yesterday. However, we are soon getting another chance for some nice auroral displays as yet another coronal hole faced our planet yesterday.

It has been many months since we've last seen a strong solar flare or even a decent sunspot region. It is no secret that we are well on our way to solar minimum. However, today exactly one year ago, our Sun looked very different compared to how it looks today. Multiple sunspot regions were visible but by far the most interesting sunspot region was sunspot region 2673. Sunspot region 2673 was on 6 September 2017 one of the most complex sunspot regions that we have seen this solar cycle and it erupted that day with an X9.3 (R3-strong) solar flare which will likely remain the strongest solar flare of the current solar cycle, solar cycle 24.

After last month's impressive G3 geomagnetic storm caused by a coronal mass ejection, it is time to welcome back a familiar solar feature on our nearest star today. We have a small coronal hole facing our planet today.

We were wrong! The coronal mass ejection we talked about back on 22 August did arrive at Earth and sparked strong G3 geomagnetic storming conditions today. A big surprise for everyone which goes to show how unpredictable space weather is.
