The photographs
below were taken during the early hours of 31 August 2003 British
Summer Time, the first cloud and work free opportunity I had
following the closest approach to Earth of the planet Mars in
virtually 60,000 years. The
red planet makes a close approach to Earth approximately once
every 26 months as it takes roughly twice as long as Earth to
orbit the sun. As the orbits of both planets are elliptical
however, some approaches are closer than others. In 1991, the
'close encounter' was nine million miles more distant than in
2003, so this year it appeared 23% larger in the sky. If you
would like to see Mars for yourself, look southeast at around
midnight if you are in the UK. It is the brightest object in
the sky at the moment, excluding the Moon, if visible.
The
last time Mars was this bright in the sky was during an ice
age, when the only humans around to see it were primitive Neanderthal
troglodytes out hunting woolly mammoth or wild deer with their
flint tools. The place where Ross-on-Wye now stands was being
formed by glaciers cutting valleys in the rock.
The
top of these views is from Bridstow Bridge and was quite difficult
to take due to traffic headlights behind me, trying to await
a gap in the traffic coming from both directions and eventually
just going ahead regardless. It is a 30 second exposure at f2.2
and the town of Ross-on-Wye appears over exposed in order to
capture the stars and Mars.
The
second and third of the views were taken by the old railway
bridge at Backney. They are virtually the same shot, however
I stood behind the camera and used a halogen lamp to light the
bridge during the second exposure. Both exposures are 30 seconds
at f2.2.
