Excellent stuff everyone - a successful night. Notice how all the early displays this year are evening events compared to the last two years which produced many pre-dawn displays.

The May 29/30th display was the best 'first' season NLC display I have ever seen. Observed from 22.30-23.45 UT, extending from W to N sky 100 degrees in azimuth from Gemini into Perseus and over 20 degrees high. Type 3 brightness with silver, white, blue, yellow, and green colours. Structures observed, bands, waves, whirls, knots. A lovely display to begin the season. Thanks to John McConnell who confirmed them for me over the phone when they first formed in bright twilight, that confirmation took about one sec!
