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.

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.

Happy New Year everyone! Congratulations on surviving yet another trip around our Sun!

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!

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.

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!

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?

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.

A familiar coronal hole is facing our planet today. You might remember this transequatorial coronal hole because it faced our planet at the end of August and caused moderate G2 geomagnetic storm conditions on 31 August and minor G1 geomagnetic storm conditions on 1 and 2 September.
