NLC Display 6-7th July 2004

Another fine display visible from my home location in Scotland occurred on the night of the 6th-7th July 2004. It first became apparent around 23:20UT on the 6th and improved steadily as the sky darkened and stratospheric cloud moved away by 00:35UT on the 7th. It was an excellent display with much structure present extending in azimuth from 280°-30° and elevation 30° at greatest. The display was active as the clouds changed appearance as the minutes passed and a feature not noted previously was an arc of light about 30° elevation centred in the NNW that moved with the sun (it was apparently not auroral) shown in the first image below.

Some of these images were featured on spaceweather.com 8th July 2004.
