For anyone getting up early to see the comet Sunday morning, there will be a pass of the ISS at 3:45 AM just above the comet in the NE. It was very bright this morning despite the low elevation. It will be obvious. Here's the pass sky chart for Salem
. Will go right by the star Capella, and also Venus/Aldebaran in Taurus.
There's another pass 90 mins later at 5:20 AM, but heavens-above thinks the sky will be too bright in Salem and Baltimore, but OK for D.C. My guess is it will be visible, so be on the lookout for it. It will be a little higher in the sky than the 3:45 pass, but generally the same NW to E, passing near Venus which should also still be visible.
