    	I just happened to read this email below as I came across your observation.
    Don't know if it applies to what you saw, but it's along the same line.

    Northern summer has arrived, and that means it's time to watch out for
    noctilucent clouds (NLCs). They snake across the sky after sunset glowing
    electric blue-white. NLCs are a mystery: The clouds hover 80 km above
    Earth at the very edge of space.  Some researchers believe they're a sign
    of global warming; others say they're caused by space dust and rocket
    exhaust. Whatever they are, they're beautiful. Historically a
    high-latitude phenomenon, NLCs have been seen in recent years as far south
    as Colorado and Virginia.

    noctilucent clouds taken this month.
