Saturday January 29 - Another Aurora

Each day on board now is much the same as the previous - we sail for a few hours, then stop and lower the CTD machine to measure the seawater which takes 4-5 hours each time, depending how deep it is - recently it has been about 4500 metres.

Fortunately, apart from the one night last week when the weather was crazy and everything got thrown about the ship, the seas are nice and quiet.

There was another aurora to watch last night - this time it lasted, on and off, for an hour and a half. The rapidity with which it changes can't be appreciated in photos, partly because each photo takes 10-15 seconds, by which time it has changed, so the photos look blurred. This picture is stitched together from 4 separate wide-angle photos, which is about 180 degrees in total - thus you can see that the aurora extends across most of the sky.
