Coronal hole faces Earth

Space weather has been very quiet lately with not much interesting to report on. There haven't been any sunspot regions or solar eruptions worth mentioning and also here on Earth we've been having quiet geomagnetic conditions. This could however change in the near future as we have a southern hemisphere coronal hole facing our planet today. Those of you who follow us on Twitter or have the SpaceWeatherLive iOS/Android app have likely seen the automated coronal hole detection alert.

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 fun! If you missed the article and like a good laugh be sure to click here and give it a read.

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 likely to be eruptive and thus launched a coronal mass ejection into space.

Coronal hole faces Earth

We are still waiting to see what the two solar flares from the past few days will cause for activity at Earth but yet another solar feature throws itself in the mix today: a coronal hole solar wind stream!

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 B6.5 solar flare on 9 March. While B and C class solar flares aren't very interesting normally, these two events showed signs that they might have ejected some solar plasma into space. Keep on reading to find out more...

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.

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 a C4 class solar flare that took place on 30/03/2018.
