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"?

    • Does anyone know if the above is taking place this year. Can't seem to find it mentioned anywhere?   Simon
    • Hello, with the weather improving, I thought I would flag up the free access to leisure centres in southwark. 1. If you are experiencing poor mental and physical health and live in the borough, the GP exercise referral service allows up to three months of free use of leisure centers. There are three levels of support, and you can even refer yourself. read more for more info: Kickstart, Active Boost and Cardiactive - Everyone Health Southwark   2. If you don't have challenges with physical ands mental health, you can access the free swim and gym for a year. for more info: Free swim & gym eligibility requirements – Leisure Facilities in Southwark 3. Are you a blue badge holder? you can apply for the AD Permit, a virtual payment which allows disabled drivers to part on single and double yellow lines without the need of displaying a blue bae in the windscreen. there is also information for disabled residents to use the Low Traffic Neighborhood (LTNs) around the borough.  Exemptions for Blue Badge holders | Southwark Council Want more information? use the councils website: www.southwark.gov.uk               
    • I am about to tomorrow. I only just realised after asking some neighbours today. Agreed that smaller households should of course pay less, like discounted council tax bills for those on benefits for example. However as our bills have gone up astronomically generally in the last few years, I do feel hardworking families are being penalised... also avid gardeners will be penalised in the summer when gardens are watered no doubt. 
    • Hello Womanofdulwich, I had a meter installed in the summer of last year. Currently my bills have fallen massively. Can you remember which month your water meter was installed? Also I received two appointments, one from a group of staff in orange who decide if the property is suitable for the water meter, and then a second appointment for the meter to be installed, did you have the same thing? Are you saying as well that you was cold called regarding the water meter, or are you saying someone from Thames water turned up, at your door unannoyed?   Lastly (so sorry to through so much questions at you) how many bedrooms do you have and how many people live at the property?
