North Northumberland is on tenterhooks again this evening hoping for a repeat of last night’s spectacular Aurora Borealis display.
The amazing Northern Lights show, the best in 20 years, started between 8pm and 9pm, reaching a crescendo between 10pm and 11pm when Lancaster University’s AuroraWatch UK alerts issued its second highest grading. But activity was still visible at 2am today in the north of the area, particularly from Holy Island.
The glowing skies are caused by electrically-charged particles from the sun entering the Earth’s atmosphere and AuroraWatch UK takes geomagnetic activity measurements to alert aurora chasers to the best places to see the display. It has four levels of activity:
Green, no significant activity, aurora is unlikey to be seen from anywhere in the UK;
Yellow, mnior geomagnetic activity, aurora is unlikely to be visible from the UK except perhaps the extreme north of Scotland;
Amber alert, possible aurora, aurora is likely to be visible from Scotland, northern England and Northern Ireland;
Red alert, aurora likely, it is likely that aurora will be visible from everywhere in the UK
Last night’s Northern Lights reached amber on the scale at its peak and, with clear skies again tonight, aurora watchers are hoping for a repeat performance.
