Science and technology have taken the guessing out of aurora watching. Satellites that monitor the sun's geomagnetic activity can predict with reliable accuracy when solar winds are bound to strike earth's atmosphere. There's even a new webcam, maintained by the Geophysical Institute at UAF, that allows viewers to see in real-time when the aurora is active. The link is HERE. We noticed last night before going to bed that the northern lights were putting on a show just after the moonrise, but I'm still playing catch-up with previous night's photos, and it was negative twenty out, so we stayed in bed.
