The effect is created by the alignment of the sun, earth and moon, and is most apparent when the moon is close to the horizon.


It's because red light (with a longer wavelength) gets bent less as it travels through the earths atmosphere than shorter blue wavelengths.


When the sun is 'behind' the earth from the moon's point of view, all the light reaching it is travelling through the earth's atmosphere. All the blue light gets scattered, but the red light charges on through in a straight line and falls upon the moon.


When the moon is close to the horizon, the low angle of view means the light reflected has to go through more of the atmosphere before it reaches our eyes - making the red effect even more dramatic!

When you are experiencing a particularly explosive 'petite mort' do you bang on about the "involuntary, or autonomic, limbic system, muscular spasms in multiple areas of the body, autonomic physiologic responses and the importance of the limbic system" or make do with an "Aaaaargh"?

    • Aria replaced our stopcock valve as it started leaking over the weekend. Came to do the work on a Sunday, very responsive to messages and efficient work - explained what he was doing and what went wrong. Highly recommend!  
    • Brilliant emergency weekend service from Aria from AFE Plumbing to replace our stopcock valve as it started leaking heavily on Saturday. He explained everything clearly and completed the job efficiently. Kind and well-mannered, would highly recommend!
    • Hello everyone, We have lost our wonderful moggie, Cookie.  She's been missing for over a week now and was lost around the back of our house on rail track land around Croxted Road/Turney Road junction. Please do keep an eye out for her and if you see her please let us know urgently as she isn't familiar with the area at all, we are very worried.  She has a microchip (with my brother's contact details) She's black with ginger/brown markings, very distinctive. If you have had sightings of her or seen her at anytime please let do let me know, Henna 07941 047094 If you could post on your local/street groups too, I'd be very grateful. Thank you!
