Daniel, 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. Best Regards, Mark ***************************************************************************************** Space Weather News for June 24, 2004 http://www.spaceweather.com 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.
