April… The month of solar minimum? 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. Space Weather Live Go to SourceRead More →
Welcome back DSCOVR! Some great news to kick of the new month with! NOAA’s Deep Space Climate Observatory (DSCOVR) satellite is fully operational again! Space Weather Live Go to SourceRead More →
Solar Orbiter successfully launched into space An American Atlas V rocket has successfully launched the European Solar Orbiter satellite into space during the early hours of 10 February. This unmanned space probe is Europe’s newest solar observatory which will start to study our Sun in just under two years from now. Its main mission is set to begin in November of 2021. At closest approach, Solar Orbiter will only be 42 million kilometers away from the Sun. Scientists hope to learn more about the solar wind, the Sun’s polar regions, the Sun’s magnetic field, solar activity and how it affects Earth. Solar Orbiter is anRead More →
Coronal hole, Transit to Solar Cycle 25 A coronal hole is facing our planet today. It is a slim southern extension of the northern hemisphere polar coronal hole. The effects of this coronal hole could reach Earth on Monday (10 February) as a high speed solar wind stream could sweep past our planet and spark some more high latitude aurora displays.

Official Solar Cycle 25 Forecast Update The NOAA/NASA Solar Cycle prediction panel has issued an official statement yesterday with news about the upcoming Solar Cycle 25. Space Weather Live Go to SourceRead More →
Welcome GOES-16! Sharp eyes might have noticed a very abrupt drop on the solar X-rays graph today. What happened to the Sun? It went into cardiac arrest? Nope. Today, December 9, the NOAA SWPC has switched to GOES-16 as the primary satellite for geostationary space weather observations. What does that mean? Keep on reading!

Cycle 25 sunspot region, Coronal hole faces Earth A small sunspot region has rotated into view on the south-east limb. No big deal you say? Well… it might be a sign of things to come! More on that later. We also have a southern hemisphere coronal hole facing our planet today which could spark some high latitude aurora in a few days time. Plenty to talk about today!

DSCOVR not to come back online until early 2020 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.

SpaceWeatherLive mobile app update 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!

Coronal hole faces Earth, Strange solar wind data? 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! Space Weather Live Go to SourceRead More →
Filament eruption, yet another CME 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. Space Weather Live Go to SourceRead More →
Faint partial halo coronal mass ejection Sunspot region 2740 has been much less active as it has been decayed the past few days. But that didn’t mean it went totally quiet. A minor eruption near the this sunspot region took place around midnight UTC yesterday and launched a faint partial halo coronal mass ejection that could arrive at Earth in a few days from now.

CME passage, G1 geomagnetic storm The minor G1 geomagnetic storm was reached earlier today at 02:20 UTC. This is caused by a coronal mass ejection passage, likely the coronal mass ejection that we posted about on 8 May. Space Weather Live Go to SourceRead More →
Faint halo coronal mass ejection A faint halo coronal mass ejection with a possible earth-directed component has been detected in coronagraph imagery from SOHO/LASCO. Space Weather Live Go to SourceRead More →
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 and several more C-class solar flares occurred as the day progressed. Space Weather Live Go to SourceRead More →
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 SourceRead More →
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 SourceRead More →
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 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.
