As we have reported before, the real time solar wind monitoring satellite Deep Space Climate Observatory (DSCOVR) which is located at the Sun-Earth L1 point is being kept in a safe hold at the moment. A glitch in its position system triggered the safe hold and that means it does not transmit any data back to Earth. However, there is light at the end of the tunnel for DSCOVR.

A familiar coronal hole is facing our planet today. You might remember this transequatorial coronal hole because it faced our planet at the end of August and caused moderate G2 geomagnetic storm conditions on 31 August and minor G1 geomagnetic storm conditions on 1 and 2 September.

Happy birthday to the SpaceWeatherLive website and mobile application! Yes, our app celebrates its first birthday today and our website has completed lap number 11 around the Sun (well tomorrow to be more precise but who's counting) and what better way to celebrate than with an update and the introduction of two highly requested features!

A T-shaped coronal hole is facing our planet today and sending a high speed solar wind stream towards our planet. High latitude sky watchers be alert for aurora in a few days time!

A small but interesting southern hemisphere coronal hole is facing our planet today.

The NOAA SWPC has issued a minor G1 geomagnetic storm watch for 5 August (Monday) due to a coronal hole that is facing our planet today.

Its summer in the northern hemisphere and that means many of us are enjoying a well earned vacation. However, the same thing can be said about our Sun. She is taking it very easy with pretty much no noteworthy eruptions or other solar events to talk about during the past few weeks. We did have the brief appearance of a sunspot region that belongs to Solar Cycle 25 but it disappeared as quickly as it appeared. Make no mistake, we are likely still at or close to solar minimum. That said, we do have something to talk about today as we unexpectedly reached minor G1 geomagnetic storm conditions yesterday and today!

It's been a little while since we've last had some news for you. Ever since sunspot region 2740 and 2741 disappeared from the earth-facing solar disk, solar and auroral activity has truly tanked back to solar minimum levels with no solar events or geomagnetic activity worth mentioning. That changes today however as a coronal hole is facing our planet today.

Strong G3 geomagnetic storm conditions were observed earlier today as a coronal mass ejection arrived at our planet.

The sunspot regions that have been facing Earth the past few days are slowly disappearing but our Sun continues to launch coronal mass ejections into space. A filament eruption took place around 19 UTC yesterday evening near sunspot region 2741 and a coronal mass ejection managed to escape the Sun's gravity.
