Marching On Together

Marching On Together I have had a romance with a lady since my childhood just like thousands of other people around the world who are also in love with her. I have remained in love with her through the many bad times and the few good times, my love for her has never faltered and never will. My lady's name is Leeds United and she is just five games away from returning to the English Football Premiership, after sixteen years in the football wilderness. In the sixties, seventies and early nineties my lady was known as "Super Leeds," however in 2003, my love was relegated from the English Football Premiership due to financial miss-handling by her owners. "Super Leeds," dropped down to the third tier of English football. If Leeds United can grab ten points from their last five games my lady will be back where she belongs in the higher echelons of English football and I can once more embrace my love with happiness.

Coronal Hole blasting Earth with solar winds traveling at speeds of nearly 800km per second causing biggest geomagnetic storms since last weeks X-class flares

After the recent historic massive X-class barrage from our Sun, on first glance, you could think she has gone back to sleep with just one lonely sunspot AR2680 on the visible surface which poses no threat for strong solar flares whatsoever.
However, our Sun is anything but asleep as a massive Coronal hole is facing Earth and is spewing a stream of solar wind which is battering the Earth's magnetosphere, see below.

The solar wind is hitting the magnetosphere at an incredible speed of nearly 800km per second, with a density of   4.7 protons/cm3, see below.

The barrage is causing an electrified gale that is sparking G2-class geomagnetic storms on Sept 16th, see the graph below. High-latitude sky watchers should be alert for auroras after local nightfall.
The geomagnetic storm is the biggest since the monster X-class flares battered Earth's magnetic field with a severe G4-class geomagnetic storm with solar winds blowing at nearly 800km/sec last week.
The severe storm was from the monster X9-class solar flare, the biggest since 2005 and the equal 14th ever recorded which exploded from our Sun on Wednesday causing wonderful auroras over Scandinavia and as low as Kentucky in the U.S.
