Comet 17P/Holmes and 8P/Tuttle
Over two months after its outburst, Comet Holmes is still visible
to the naked eye, slowly moving about the northern sky, slowly growing
even larger, and also slowly fading. On the other hand,
Comet Tuttle, another periodic comet, is rapidly brightening
and speeding by, spending only a few days in this part of the sky.
