This time last week the Earth arrived at its vernal equinox where some of us in the Northern Hemisphere were treated to a rare Solar Eclipse as a Super Moon drifted in-front of the Sun. In a lightly cloudy Edinburgh, Scotland, we managed a 95% partial eclipse revealing a beautiful crescent.
At the same time as I was taking this photo, a south facing prototype Lightlog was quietly sitting on a window shelf enjoying a lovely day’s worth of light data including its own view of the very same eclipse.
The first image below shows a spectrum visualisation of the received light; the image below that is an enhanced colour version using the same data. Notice how the blue day light desaturates around 9:35am as the Moon’s disk (almost) covers the Sun.
The ‘spikes’ in the data are caused as the day’s partial cloud cover drifts over the sun, a clear blue day (as viewed from this stationary Lightlog’s south facing window position) would show a beautiful smooth arc between sunrise and sun set.
