I saw it tonight, @ 5:45 p.m., dusk our time, very bright above the WSW horizon. Very bright.
Thanks.
As of Jan 12th it's now @ -4.5 MAG , which makes it number #2.

We still don't have data to establish the size of this giant that is now coming downward to sol.
Have you seen the real-time SOHO L-3 images ?
It's BIG (Planet-size?)
