AURORA SURPRISE: A co-rotating interaction region (CIR) hit Earth's magnetic field on Jan. 25th. The impact sparked an unexpected display of auroras over Iceland. "A magnificent arch began glowing from east to west," reports Christopher Mathews from Hraunborg (near Reykjavík). "Soon it split into multiple streamers and lit up the night!"

Solar flux for Friday and Saturday 113.4 and 125.3 respectively.

The running 27 day (one solar rotation) mean, having risen above 100sfu on Boxing Day, remains above that level. Having peaked at 111sfu, it was on its way down but is now increasing again, currently 103sfu.

"I had just finished a star gazing talk on the Viking Venus cruise ship when the CME arrived," reports Terence Murtagh. "The sky filled with fantastic fast moving dancing auroral arcs."

"Despite the vessel ploughing through rough seas and strong winds en route to Trondheim, we managed to catch some worthwhile snaps," says Murtagh. "Here's hoping for clear skies on Feb. 2nd [in case a real storm materialises]."

AURORAS IN THE USA: On Feb. 3rd, a crack opened in Earth's magnetic field. Solar wind rushed in to fuel a display of auroras across several northern-tier US states. Kevin Palmer sends this picture from Sheridan, Wyoming:

Sorry guys had a bad week, last Saturday we had some high winds, one gust took out half next doors fence, next gust took the other half and all but 2 of our ridge tiles, some slates and the gutter... Been in wrangles with insurance since.

Sunday saw more high winds which obliterated next doors shed!!

Anyway...

AURORAS IN THE SNOW: "Snow flurries and aurora flurries battled it out for night sky supremacy on Feb. 4th near Trapper Creek, Alaska," says aurora hunter Todd Salat. He's happy to report, it was a tie:

INTERPLANETARY SHOCK WAVE SPARKS COLOURFUL AURORAS: This was not in the forecast. An unexpected interplanetary shock wave hit Earth's magnetic field on Feb. 11th: data. The impact sparked a G1-class geomagnetic storm and some very colourful auroras inside the Arctic Circle:

Insurance still giving us the runaround...and more bad weather inbound this week....fingers crossed the rest of the roof stands up to it!!

AURORAS AND METEOR SMOKE: On Feb. 10th, a G1-class geomagnetic storm erupted. Danish photographer Ruslan Merzlyakov was hurriedly setting up his camera to catch the auroras when he was interrupted by a fireball. "A bright meteor streaked across the sky," he says. Back to work, he took this picture:
