I live in Sandy near Little Cottonwood Canyon. The city's "glow ball" lighting system does a great job of lighting the bottom of airplanes (ugh) but it also lights up flocks of birds travelling overhead. Anyone know what type of birds are flying by at night? I was out last night bumping around some Messier objects around 10pm before the moon kicked in and there were numerous flocks of birds slipping through my eyepiece view. The city glow illuminated them well. They seem rather high in altitude. They were light in color. Possibly white. I'm assuming a smaller bird from their movement and they traveled in a loose "V" or "W" when in flock. I saw them a number of times last year too. Anyone else see these night travelers? Anyone know who they are? Just being Mr. Curious! Thanks! Bruce Hugo
