Auroral storm
Kp value of 7. Aurora visible all across UK. Not here overlooking city of London. Everywhere though!

Aurora borealis
Last night 143 students and teachers witnessed an amazing auroral show. This first picture shows the greens, pinks and yellows. More to come.

Science Week at Nonsuch
Get out your planner...
Book in Friday 1.05pm on the 21st March for a keynote speech from Dr. Nick Achilleos from the UCL Centre for Planetary Sciences. He has been working on the Cassini probe around Saturn and is currently designing a mission to Ganymede - the largest moon in the Solar System orbiting Jupiter every seven days.
Artists's Conception of Cassini Saturn Orbit Insertion
Image of Ganymede's anti-Jovian hemisphere taken by the Galileo probe. Lighter surfaces, such as in recent impacts, grooved terrain and the whitish north polar cap at upper right, are enriched in water ice.

Maunder Minimum link to the Little Ice Age?
There is still a very poor understanding of the correlation between low sunspot activity and cooling temperatures. During the period 1645–1715, in the middle of the Little Ice Age, there was a period of low solar activity known as the Maunder Minimum.
The Spörer Minimum has also been identified with a significant cooling period between 1460 and 1550. Other indicators of low solar activity during this period are levels of the isotopes carbon-14 and beryllium-10.
On the other hand, in a 2012 paper, Miller et al. link the Little Ice Age to an "unusual 50-year-long episode with four large sulfur-rich explosive eruptions and notes that "large changes in solar irradiance are not required."
What do you think?

Solar Activity
Using helioviewer.org our Y10 students imaged the Sun in multi-frequencies last week. We're looking out for solar activity, hopefully a CME heading our way, ready for our trip to seek out the Northern Lights in two weeks.

We are hoping for good solar activity and the magnetic field Bz aligning south. More at http://rossellet.com/aurora_tracker.htm
