Coronal hole faces Earth

Coronal hole faces Earth

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.

Today one year ago: X9.3 solar flare

Today one year ago: X9.3 solar flare

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.

Coronal hole faces Earth

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.

Strong G3 geomagnetic storm

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.

What's the buzz about? CME aimed towards Earth?

What's the buzz about? CME aimed towards Earth?

A buzz started to develop in the space weather community about a possible earth-directed coronal mass ejection. We took a look at the event and weren't impressed but considering it is solar minimum and there hasn't been much to get excited about, we do a short analysis anyway.

Coronal hole faces Earth

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!

Coronal hole faces Earth

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.

Welcome to August.... and solar minimum?

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.

Coronal hole faces Earth, G1 watch issued

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.
