On the evening of our arrival at Muka I observed what appeared like a display of Aurora Borealis, though I could hardly believe that this was possible at a point a little south of the equator. The night was clear and calm, and the northern sky presented a diffused light, with a constant succession of faint vertical flashings or flickerings, exactly similar to an ordinary aurora in England.
