At the moment, Venus is visible in the sky at dusk after sunset.
As seen from the Earth, it is making its way 'round its orbit
and by June 5th it will pass in front of the Sun...
... a rare transit that will not occur again until the year 2117.
This is the last time she will do so in my lifetime.
[File under: Things I should not take for granted.]
And so it is time to calibrate telescopes heavenward
and gaze into the early evening sky.
