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

The NOAA/NASA Solar Cycle prediction panel has issued an official statement yesterday with news about the upcoming Solar Cycle 25.

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.

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!

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!
