The NOAA SWPC has issued a minor geomagnetic storm (G1) watch for this Thursday (22 October) as a high speed solar wind stream from the northern polar coronal hole is expected to arrive at Earth. This is the same coronal hole which caused multiple days with geomagnetic storm conditions (G1-G2) last month and produced solar wind speeds around 650km/s at our planet.

Breaking news today from the Solar Cycle 25 Prediction Panel! It is now official, the solar minimum between Solar Cycle 24 and 25 took place December 2019 when the 13-month smoothed sunspot number fell to 1.8. This means that we've been in Solar Cycle 25 since December 2019!

A coronal hole is facing our planet today. While this coronal hole is poorly defined in the sense that there is not one large opening, we do see several openings (dark areas) which combined cover a significant portion of the Sun's northern hemisphere. We even see an opening near the equator that has already passed the central meridian.

A C2.0 solar flare took place this morning at 06:47 UTC from a plage region (a region without sunspots) near the west limb. A small coronal mass ejection was ejected into space but it is not aimed towards Earth. This event was kind of a wake up call as there has been little space weather activity worth talking about in the past few weeks...

The recent M-class solar flare from a sunspot region that belongs to Solar Cycle 25 was a wake up call for everyone who keeps an eye on the weather in space. Who would have thought that we would see an M-class solar flare while we are so close to solar minimum? Not many of us that's for sure. It raises yet again the question... When is solar minimum, or when was solar minimum? Could we have passed solar minimum? We have seen a couple of Solar Cycle 25 sunspot regions during the past few weeks and this M-class solar flare was another sign that we might have passed solar minimum already? Is Solar Cycle 25 really starting to gain traction? In this news item we will take a look at the evidence and present you with the data we need to draw a preliminary conclusion.

The sunspot region that was responsible yesterday for what could be the first M-class solar flare of Solar Cycle 25 has now rotated into view.

925 days. That is the amount of time we had to wait since we last saw a M-class solar flare on the Sun. But today the wait is over. An impulsive M1.19 solar flare (minor R1 radio blackout) took place on our Sun this morning peaking at 07:24 UTC. NASA's Solar Dynamics Observatory seems to have taken a break from its sun-watching duty for some reason but STEREO Ahead captured the impulsive eruption confirming it comes from a sunspot region near the east limb from Earth's point of view. This sunspot region very likely belongs to Solar Cycle 25 due to its high latitude and it could even be the first M-class solar flare of Solar Cycle 25 depending on if we have passed solar minimum or not.

Time flies. Another month has passed and summer along with shorter nights is closing in for us northern hemisphere sky watchers.

Some unexpected action yesterday! The minor G1 geomagnetic storm threshold was reached on two occasions yesterday (10:44 UTC and 14:18 UTC) and a coronal hole faced our planet! Where did this mysterious geomagnetic storm come from and what can we expect from the earth-facing coronal hole? Keep on reading to find out.

Hello everyone and welcome to April. Could this month be a turn around point for us solar watchers? Is Solar Cycle 25 about to start? Understandable questions which we will shed some light on later in this article.
