Coronal hole faces Earth

Coronal hole faces Earth

Space weather has been relatively uneventful this week. Our Sun is quiet as we are close to solar minimum. No sunspot regions could be found on the earth-facing solar disk this week. We do see two small bright regions on STEREO Ahead but they look small and inactive. When it comes to auroral activity we do see a slight enhancement in the solar wind data right now but the north-south direction of the IMF (Bz) is mostly northward so enhanced auroral activity is unlikely tonight. However, if you follow us on Twitter or have the SpaceWeatherLive iOS/Android app installed you might have received an alert that we have a coronal hole facing our planet today!

Solar Orbiter successfully launched into space

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 an ESA mission with strong NASA participation.

Coronal hole, Transit to Solar Cycle 25

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.

Welcome GOES-16!

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!

Coronal hole faces Earth

A familiar coronal hole is facing our planet today. This is indeed the coronal hole that has been the source of quite a few geomagnetic storms during the past few months.

Cycle 25 sunspot region, Coronal hole faces Earth

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!

Coronal hole faces Earth, G1 watch

Coronal hole faces Earth, G1 watch

A large coronal hole is facing our planet today. Most of you might remember this coronal hole as it is the same coronal hole that faced our planet on 28 August and 24 September. This coronal hole has always been a reliable source for geomagnetic storm activity a few days later. What can we expect this time around?
