Thanks Cliff,
It is not as easy to observe in the early hours as when I was younger.
I also had a dentist trip last week. Not as good as your visit. It is like keeping an old car working.

Another NLC observation.

2018 June 25/26 01.11 UT to 02.17 UT
Initially weak to 5 degree maximum elevation.
But by 02.17 UT another major display.
Many bands, small veil.
Transparency good.
Extensive bright display to 28 degree maximum elevation.
Azimuth 335 degrees to 035 degrees. Buildings/trees blocking both ends.
Getting brighter, higher and more extensive with time, but I had to pack it in.
Only slept 3 1/2 hours.

8x32 binocular and unaided eyes.
Took photos also.

Regards,
David
