    Hi All,
    Superbird A (#20040) has now returned to eastern U.S. skies,
    with flashes starting tonite (March 27 local, March 28 UT) at
    the southern tip of Florida at around 2:46 UT and working
    their way up the Atlantic seaboard to Newfoundland at 3:01 UT.
    Atlanta's flashes should be centered at 2:50 UT tonite,
    Washington D.C. at 2:52:30, New York City at 2:54, and
    Boston at 2:55.  Flashes should be visible as far inland
    as the line from central Alabama to lower Michigan.  Cleveland's
    peak will be at 2:53 (though the elevation is only about 8
    Flash location is low in the east around RA 14h 53m,
    Dec -3.6 (for D.C.)  Other locations will vary slightly in
    declination depending on latitude (e.g. Miami flash location
    is RA 14h 53m, Dec -1.7).  Nearest bright star is mu Virginis
    (mag 3.87) which is a couple degrees to the southwest (i.e.
    to the right) of the flash location.  Beta Librae (m 2.61)
    is about 8 degrees directly below the flash location.
    If you miss it tonite, don't sweat it.  It will be visible
    each night for at least the next month, and the elevation
    will be steadily improving due to the satellite's slow
    westward drift.
    Current rotation period is 22.84 seconds, with flashes on
    the half-period visible during the middle of the ~6-minute
    flash window.
