We are still under the influence of the waning effects of a solar wind stream from a coronal hole but the party isn't over just yet: another coronal hole is facing our planet today and sending yet another high speed solar wind stream towards our planet!

We are approaching solar minimum so sunspots and solar flares have become a rare sight. Even coronal holes have migrated to higher latitudes but we are in luck today as a southward extension of the northern hemisphere polar coronal hole faces our planet today.

This morning at 07:31 UTC, NASA launched the Parker Solar Probe into space. While the launch was postponed on Saturday, everything went according to plan on Sunday and the Parker Solar Probe is now on it's way towards the Sun.

Welcome to August! The year 2018 is now 212 days old and according to the numbers from the NOAA SWPC, the Sun has been spotless during 120 days this year thus far. The sunspots regions that did face Earth this year have been far from impressive and we had no M or X-class solar flares yet this year.

It is summer in the northern hemisphere. While solar activity has been very low the past few weeks as we are crawling towards solar minimum, the Sun is actually doing its mighty best here in Europe with scorching temperatures throughout large parts of Europe. However, we were notified today by our very own alert system that we have an interesting solar feature on the Sun today. Indeed you guessed it: a coronal hole is facing our planet today and sending a fast solar wind stream towards us.

The NOAA SWPC has a minor G1 geomagnetic storm watch in effect for Wednesday, 27 June.

The beginning of June has been very quiet when it comes to space weather. While we did reach minor G1 geomagnetic storm conditions back on the very first day of this month, no other space weather events have occurred which are worth mentioning. The solar wind conditions at Earth have been very underwhelming for a while now and the Sun has also been very quiet as we are starting to reach solar minimum conditions. That said, our automated coronal hole detection system spotted an opening in the corona yesterday. A southern extension of the northern hemisphere polar coronal hole was facing our planet today.

Sunspot region 2712 didn't manage to develop further since we wrote about it yesterday and has been pretty quiet today with only a couple of B-class solar flares. However, sunspot region 2712 is not the center of our attention today. Indeed, a coronal hole takes the spotlight today. A southern hemisphere coronal hole close to the solar equator is facing our planet today and sending an enhanced solar wind stream towards our planet.

Summer is upon us in the northern hemisphere and that means very little aurora sightings. The fact that we are in a very quiet space weather period doesn't help either of course but after a long and cold winter these warm rays of sunshine are very much welcome. Right? Or are you starting to experience aurora withdrawal symptoms? Either way, something has been drawing our attention today and that is the Sun's X-ray output as measured by GOES-15. Indeed: we are talking about solar flares.

A lot of aurora enthusiasts have put 17 May in their agenda as a possible date for some enhanced geomagnetic activity and thus auroral displays. Why? Because that is the date that a coronal hole solar wind stream is expected to arrive at Earth from a coronal hole that managed to give us moderate G2 geomagnetic storm conditions back in April.
