I've noticed recently a great number of posts are being added during times when I am away "in the land of Nod". These posts are appearing at any time between midnight and 6.00am.

I find this intriguing! Is it just that the aeromodelling fraternity contains an inordinate amount of insomniacs, or if they are of a 'certain age' such as myself, find themselves visiting the smallest room in the house several times during the night, and, failing to return to the arms of Morpheus, are turning to the forum for solace?

If I get called out once I've sorted out the work issue I'll quite often wind down by checking the site and can be posting anywhere from midnight through to 4:30 or so.

It's not by choice I'm up late, but I quite often read and post in forums at 2am whilst comforting the baby on my shoulder!

I'm often on here after midnight, not usually later than 1am though. On the other hand, you won't usually see anything from me before I'm home from work during the week, or before about 10am at the weekend.

I'm rarely in bed twice the same day now I'm retired Rarely in bed before 1am. In fact it was 2.30 on Wednesday

When I was working I was up just after 6am and on my bike by 6.30 for my 13 mile cycle commute. So I CAN get up early if I really have to (and I actually enjoyed my ride, even in bad weather ... usually) but now I don't have to, I don't. As someone once said "To be abed after midnight is to be up early".

Sadly I am awake by 6am almost every day.

I do try to stay off the pooter that early in the morning as I generally go and feed the chickens and potter in the shed or garage until it is safe to wake up SWMBO with a cup of tea.

It's a cunning scheme to confuse those living on the Greenwich Meridian by those of us who are 12 hours ahead!

And it should still be GMT not UTC. For all those who decided to change it the meridian still goes through GREENWICH thinking

Weeellllll,... strickly speaking its doesn't anymore and hasn't for some time now. Yes, it does go through the district of Grennwich but it doesn't go through the spot where all the touristists stand "with one foot in each hemisphere" to have their photos taken!

The reasons for this are very technical, but it is all to do with what geometric model you approximate the shape of the earth with. When the original Greenwich Prime Meridian was set up a (by modern standards) quite simple geometric model - known as the geoid - was used as the basis for calculation. Over the years errors have been found in this model and new models developed - of which there have been many.

Not the most recent, but certainly the most commonly used, is WGS84 (so called because it was agreed by an international treaty in 1984). This incorporates all sorts of very complex second and third order effects on the geooid for gravitation, tidal forces, ground density etc etc. There have been later geoids that are even more accurate, but it is possible they may never be adopted, instead correction factors calcaulted using them will probably always be applied retrospectively to WGS84. Why? Simple - the GPS system is based on WGS84 and the there is a huge amount of investment in that and systems that use it (a bit of which we have!) And so cmpatability means we might be stuck with it.

So what's all this got to do with Greenwich and the Prime Meridian? Well this,...under WGS84 the actual prime meridian runs about 200yards to east (if I remember correctly) of where the origanal Prime Meridian was! If you ever go to Greenwich you can prove this to yourself. Put your GPS on Lat/Long display, stand on the so-called Prime Meridian and it will tell you that you are a few seconds west! Of course everyone assumes that it is an error in their GPS - it isn't!

BEB, thank you for the educational talk. A new understanding gained, funny thing I can navigate, using marine charts, a sextant if necessary, pilotage, and of course a satellite navigator. I am aware of the WGS84 meridian, you have to be careful using a satellite navigator on non WGS84 charts, and there are a lot of them, as hitting a cliff is not good. Your claim the cliff has been moved does not wash.

But I never knew where the meridian came from.

I'm an odd insomniac! laugh

If my brain starts thinking about anything it won't shut up and can go on all night sometimes. Sort of like being in a noisy room. Oddly enough it's not just getting to sleep that causes me problems. I can be asleep for a couple of hours and just keep waking up, then try to get to sleep again. Sometimes I give up and just go on the internet or out to the shed for an hour or so.

Very rarely feel tired though. A few years ago I would sometimes be awake all Friday and Saturday night finally getting some sleep on Sunday afternoon/evenings but thankfully that hasn't happened for a while!

Know what you mean Chris, I keep searching for the "sleep switch" to, not really insomnia more like interrupted sleep or sometimes interrupted dreaming I know how you feel.clock
