SpaceWeather.com -- News and information about meteor showers, solar flares, auroras, and near-Earth asteroids is currently reporting the cloud from the Russian volcano in the Pacific is streading around the northern hemisphere and I've noticed the dusky red sunsets of late and very red gibbous moon the night before last.
This early morning, after a bathroom 'break', I witness this horizontally streaked northern sky from the bedroom window 90 min before sunup - enhanced in the photo with an 'edge-filter'. The 2nd photo shows an enlargement above the central tree and close wavy bands.
Anyone else notice unusual twilit skies of late?
ps: seen no blue noctilucent clouds at 80km now for fortnight

but this a fair substitute
