For those who enjoy seeing objects that cross paths or pass "in formation",
like the NOSS satellites, there are 2  such opportunities for the East Coast
USA on Monday evening.  

The crossing involves the Mir and USA 69 which will occur in the ESE at
19:24:10-19:24:30 EST [00:24:10 UT] depending upon your location.  South of
Washington, DC (Atlanta, eg) it will occur about 10 deg above the horizon and
will not be particularly close (5 deg apart).  From Boston to Washington it
should be visible at 1x.

About 9 minutes later also in the eastern sky,  Landsat 4 and Ariane 40 R/B
will traveling on the path within a degree of each other from about 19:32EST
until the end of the pass.  Boston and NYC will have about a 2 deg vertical
separation.  For Philadelphia to Atlanta they will be closer.

Here are the elsets used for these predictions
