It is BARELY naked-eye visible in the North — and it is very low, in the very early mornings — in the NW sky.
Very low & borderline naked-eye.
It could — it should get — brighter. Perihelion is on May 27, 2010. 10-days away.
On May 13 it was at its closest to Earth.
Fingers crossed. It is up there. Just not that visible.
This has been the story, when it comes to comets, in the Northern Hemisphere.
