have been asked by a solicitor to find out at what rate the sun sets
in Coventry between 7pm and 8pm on 3rd June.
I have been asked by a solicitor to find out at what rate the sun sets

I guess the question is about angle of elevation above the horizon i.e.

angle of fall per time unit?


It's for a court case up and coming this month, so I would appreciate
some help please.


Thanks

You could try this sun angle calculator online, plug in lat and long
details, time and date, I think it's the "True Elevation" figure you need:

I suspect you will need an expert witness statement for this information to
'stand up' in court!

I know the Met Office does provide some legal services, but not sure about
the sun position information - they may be able to point you in the right
direction, however!

Steve,
I guess the basic answer must be 15 degrees per hour - which will
be constant throughout the day (and night). I sure hope you'll charge the
solicitor whatever he would charge you!

That won't be the rate at which the altitude (elevation) angles decreases
with time. You are referring to the compass direction of the sun. The
elevation change would be fastest around 18z and then decrease as the
evening progresses. The path of the sun is easiest seen as a sine curve.

Hi Steve,

I got the following from the "Starry Night" program:

Time - 1900 Altitude 18deg 10min Azimuth 288deg
Time - 2000 Altitude 9deg 31min Azimuth 294deg
Time - 21hr 18min Sunset Azimuth 309deg.

This is for the 3rd June 2006 at Coventry - all times clock time.

So I suppose you could say that the sun is sinking about 8 degrees an hour,
although it does not seem to be quite a constant rate if you work it out. I
can't see why that should be, but anyway now your solicitor owes you instead
of the usual other way round.

For a solicitor a diagram might be more useful. I can email you sun+star
charts for the requested times if you like. (Location Coventry Airport
