Sunspot region 2740, C9.9 solar flare

Sunspot region 2740, C9.9 solar flare Almost an M-class solar flare! Sunspot region 2740 (Beta-Delta) produced a very impulsive C-class solar flare this morning at 05:10 UTC. The solar flare peaked at an X-ray flux of C9.97 which is just shy of the M-class threshold. The eruption was associated with an Type II Radio Emission […]

Far side fireworks

Far side fireworks Not much to report on the earth-facing side of the moment but the Sun’s backside has sprung back to life with two distinct areas firing off eruptions. Space Weather Live Go to Source

New page: GOES solar images

New page: GOES solar images With the introduction of GOES-16, the NOAA SWPC provides us with yet another valuable solar watching sentinel which will undoubtedly be of great use when solar cycle 25 begins. Space Weather Live Go to Source

April Fools, Coronal hole faces Earth

April Fools, Coronal hole faces Earth Yesterday’s article about NASA launching a satellite to close solar coronal holes in order to make human missions to Mars possible was of course the SpaceWeatherLive April Fools prank. It was entertaining to see all of your responses and a couple of you even fell for the prank. Great […]

C4.8 solar flare

C4.8 solar flare A new sunspot region that received sunspot number 2736 earlier today erupted with a long duration C-class solar flare. The solar flare peaked at 11:18 UTC and reached a maximum X-ray flux of C4.8. The eruption was associated with a Type II radio sweep which indicated straight away that this event was […]

Eruptive flares, NOAA G1 watch

Eruptive flares, NOAA G1 watch The past few days, sunspot region 2734 faced Earth. While the sunspot region wasn’t very complex it was the first proper sunspot region in quite some time and produced a couple of small solar flares. The two most noteworthy events were a C1.3 solar flare on 8 March and a […]

Coronal hole faces Earth, G1 watch

Coronal hole faces Earth, G1 watch It’s that time of the month again as we have a familiar coronal hole facing our planet today that should influence the solar wind environment around our planet for a couple of days at the end of this month, and the beginning of next month. Space Weather Live Go […]

C5.0 solar flare

C5.0 solar flare A sign of life from our star! Sunspot region 2733 erupted with a C5.0 solar flare today at 13:22 UTC. While not the kind of solar fireworks like M or X-class solar flares, this is a fairly decent solar flare during solar minimum. In fact, this is the strongest solar flare since […]

Solar Cycle 25 and the 10.7 cm radio solar flux

Solar Cycle 25 and the 10.7 cm radio solar flux Following our previous guest post regarding the upcoming Solar Cycle 25 we have yet another guest post. This time from Patrick Geryl. Patrick does research in astrophysics, especially everything related to the Sun. He has currently published 3 articles on Researchgate. At this moment he […]

Are we at the beginning of Solar Cycle 25?

Are we at the beginning of Solar Cycle 25? We are doing something new today, a guest post! Good friend of the website Christian Harris who is a passionate hobby astronomer and very knowledgeable in the field of space weather started a great discussion on Facebook about something which could signal that we are at […]

Minor G1 geomagnetic storm

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. […]

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 […]

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. Powered by WPeMatico

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. Powered by WPeMatico

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 […]

Coronal hole faces Earth, G1 watch issued

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 […]
