Did anyone else notice the electric blue noctilucent clouds over SLC very early this morning? They are uncommon, here's a recent story from the S&T website about them: https://www.skyandtelescope.com/observing/noctilucent-clouds-3/ I'm going to see if they come back tomorrow morning, this is only about the third time I've seen them in my life, and the first time over the Salt Lake Valley. If I had been more awake, I would have tried for pics.
