Equinox vs Equilux

20th March 2018

Officially the first day of Spring today as it is the equinox – at 4.15pm precisely! The astronomical equinox is when the sun is directly over the equator. However, the day when there is equal day and night length (in Torridon) was last Sunday. This is the equilux and usually differs in time from the equinox due to the angular size of the sun (depending on latitude) and atmospheric refraction. Well there you go!

Spring Quiz Below, the last 3 photos, taken today on the slopes of Fionn Bheinn above Achnasheen, pose questions. The answer to each photo/question will be posted tomorrow.

Otherwise, it was a lovely day with good views and firm snow at all levels and aspects. Good snow cover remains above 650m.

The big vista looking south over Achnasheen, with the hills of upper Strathconon on the left to the hills of Glencarron, Glenuig and Monar on the right.

The big vista looking west from the slopes of Fionn Bheinn. Name them hills. There are 5 (possibly 6) Munros and 2 Corbetts in the photo. Not part of the ‘official’ quiz, but fill yer boots!

Unfortunately, Spring heralds the time of uncontrolled muir burning in the North-West Highlands….

Q1 What are these lines and holes on the grass?

Q2 What are these black streaks in this grassy hillside?

Q3 What snowpack feature is this?

      Nice one Bruce. Correct, but rather Vole tunnels than field mouse. Cheers, Andy.
