    East coast US: Space station and near Earth asteroid tonight
    From: Frank Reed

    Observers in the eastern US tonight have a nice opportunity to see the ISS (International Space Station) tonight a few minutes before 6:30 Eastern US time. At 6:30 the station will be entering the Earth's shadow so that is the limit for all observers. Observers in the South will see a pass nearly from horizon to horizon. Here in RI the station will sink into the shadow shortly after passing the zenith. The ground path from runs from Georgia toward Maine. Details at heavens-above.com (note: change the lat/lon in this web address to your own location).

    Also, observers globally with access to a medium-sized telescope capable of seeing stars as faint as magnitude 10.5 can watch a near earth asteroid pass about a million miles away. That's close enough that the apparent angular motion will be quite fast: 2.2 minutes of arc per minute of time. Today is the best opportunity by far though with much larger scopes it will be visible for several days. Details at S&T. Luckily it's forecast to be very cold tonight here. I call that "luck" because part of the explanation for the cold air is "radiative cooling" --in other words, clear skies. A rare thing in January in New England.
