    Hi Guys,
        Anybody got the gear to observe this?
    
        Cheers, Geoff.

    At 04:46 Saturday Morning  Eastern Standard Time we will turn on
    the lasers on the ANDE MAA satellite as it comes over the
    WashingtonDC area.  
    
    This is a horrid hour, and we do not expect anyone to look or to
    waste sleep trying, but we figured we should alert the amateur
    list just in case... Someone had an interest.
    
    Remember that these are not visible lasers, but 800nm (infrared
    below visual red).  They would need a CCD and large telescope to
    detect them.  They will be pulsing several times a second for 3
    to 5 minutes.  We do not expect any amateurs to see them nor to
    even look for them.  
    
    Just wanted to give you a heads up.  Oh, and we had the wrong
    names on the wrong objects so the object with the lasers on it
    is ANDE MAA which is now object 29664 .
    
    The ANDE telemetry on 145.825 should show when the command is
    successful.  You would see a packet coming back from ANDE saying
    LEDS WAS OFF (meaning it just switched to ON).  Those of you
    with familiarity with the Kantroincs TNC (that is all ANDE is)
    will notice that all we did to control the lasers was to hook
    them to a switch hooked to the front panel POWER LED.  Since the
    Kantrnoics TNC has a LEDS OFF command to save power when the TNC
    is in a low power application, we set the default to be LEDS
    OFF.  This way, we can use that command to turn on the 6 Watts
    worth of lasers easily.
