Periodic comet 96P Machholz is inbound on its return journey around the sun. It has been detected by some ground based observers already, the last I can find says it is already at magnitude 13 in early morning southern skies.
This comet is very active and has been seen to have very long Ion and dust tails. These images are from the last return, 2007 April, which was seen in the STEREO HIA solar imager.
