Details:
A fine display last night from Churchill, Manitoba, on Jan 27, despite the tapering off of the impact from the coronal hole earlier in the week and a Kp index of only 2. The auroral arc and oval was well-defined and got quite bright about 8:30 to 9:30 pm Central Time as the auroral arcs brightened from east to west. The display then weakened but always covered much of the sky. A time-lapse taken over 3.5 hours showed waves of aurora pulsing down from the north. But the display never re-brightened significantly. However, it put on a good show for our guests at the Churchill Northern Studies Centre, on a clear windless night at -20° C.
