Sun in the west peeked through storm clouds in the late afternoon, and a bright double rainbow appeared in the east, visible all over Halifax. Caught the full arc from work with the wide angle lens of my GoPro:

Rainbow Over Halifax

Probably the brightest rainbow I’ve seen, with the pronounced inner brightening clearly visible. Note the helicopter just inside the outer rainbow, to the left. (Might need to view this at full size to see it.)
