The anticipated coronal hole solar wind stream has finally arrived at our planet.

A shock like structure arrived yesterday at 23:21 UTC at DSCOVR when the solar wind density abruptly rose to about 40/cm3 along with a minor but also abrupt increase in the total strength of the IMF. These are signs you'd normally expect of a CME but its safe to conclude this is indeed the coronal hole solar wind stream. It is rare for a coronal hole solar wind stream to form a shock wave at AU1 but not unheard of.

The solar wind stream comes with some interesting IMF parameters as well as the north-south direction of the IMF is holding steady around -10nT. Active geomagnetic conditions have been observed but minor G1 geomagnetic storm conditions are possible in the hours ahead should the current numbers hold and the solar wind speed start to increase.

A coronal hole is facing our planet today and an enhanced solar wind stream is expected to arrive at Earth this Thursday. Read more on our website!

We are slowly seeing the onset of the anticipated coronal hole solar wind stream. The solar wind data hasn't shown us anything impressive just yet but keep an eye on the data to see how the situation evolves in the hours ahead. Any auroral activity will for now be confined to arctic latitudes but an increase in the geomagnetic activity is expected as the NOAA SWPC has issued a minor G1 geomagnetic storm watch for tomorrow (10 April) and Wednesday, 11 April.

Following our news item that we posted yesterday, the NOAA SWPC has issued an official minor G1 geomagnetic storm watch for 10 April (Tuesday) as an expected coronal hole solar wind stream is expected to arrive at Earth on this date.

The video below shows the coronal hole on SDO's AIA 211 Ångström wavelength as it rotates across the Earth-facing solar disk.

A familiar coronal hole has returned! This coronal hole was responsible for some nice auroral displays last month and a short-lived moderate G2 geomagnetic storm!

What can we expect this time around? Read all about it on our website!

After literally months of planning, brain storming, coding, translating and fighting over the tiniest details, we are very proud to present to you a brand new front page for SpaceWeatherLive.com!

Go check it out and read our news article for details on what we changed and why! Please let us know in the comments what you like and/or dislike about the new front page, your input is invaluable!

A big thanks also to our translators who did a fantastic job in a short amount of time and of course a select few of you that we've asked for input during the past few months. Thanks!
New front page!

A southern extension of the northern hemisphere polar coronal faces Earth today. Could this be yet another opportunity for high latitude sky watchers to capture some nice auroral displays? Read our news article on the website!

Another night is upon us with possible enhanced auroral displays at high latitudes.

The north-south direction of the IMF (Bz) has been southwards now since a couple of hours around -5nT while the solar wind speed has been creeping upwards to a value of around 450km/s right now.

High latitude sky watchers might see scenes like this with a little luck. Bob Kelley from Alaska captured this image yesterday and calls it an Aurora Angel. Amazing work! Well done!

Congratulations to the folks from Flight to the Lights for yet another success story!

Flights of the Lights is literally that. A flight in a chartered airplane high above the southern ocean, in the dark of night to spot the southern lights.

Today they had their second flight ever and it was a great success. Here is an image that Brad Phipps took somewhere high above southern ocean. Amazing work and congratulations again!
