Today 16.10.2017, an “unusual” reddish sky and red-looking sun has been seen across many parts of the UK!
The reason why….
Ophelia originated in the Azores where it was a hurricane and as it tracked its way northwards it dragged in tropical air from the Sahara.
This meant that dust from the Sahara was brought with it.…
The dust gets picked up into the air and goes high up into the atmosphere, and that dust has been dragged high up in the atmosphere above the UK.
The particles in the air cause blue light to scatter, leaving longer-wavelength red light to shine through.
