Arapuni is a rural town centre on the Waikato river in the South Waikato District of New Zealand.
The video speed is 30X normal, meaning that about an hour was compressed into just over two minutes. There is a short real-time piece at the start, to set the scene.
The day started with a veiled sunrise and then a blanket of quilted grey-white cloud covering most of the sky.
It was a more or less featureless cover, looking vaguely like a quilt of diamond shapes with their sides at roughly 30° to horizontal.
Around noon or so, the cloud cover split to the Northeast, not quite vertically.
The cloud on the North side of this split featured many fine horizontal lines similar to a venetian blind.
The cloud on this side seemed to roll back on itself, coming from the left in the foreground and doing a U-turn to disappear behind itself.
Meanwhile, in the gap which was widening into a huge “V” shape, lots of various formations were occurring. Some were rows of similar shapes forming out of the available aerosol particles.
There were some fine curved ripples and some rows of broken lines in the background.
The bank of cloud coming from the right (southeast) in the video started turning back on itself as the left-hand mass also had.
Towards the end of this video, a large cloud of aerosols rises from the lower right, forming a grey plane of narrow lines in a “fingerprint-like” pattern.
