Hi neighbors,

Tomorrow (Tuesday) the planet Venus will cross the sun's disk.

Such "transit" events are rare and amazing to watch -- you can
actually see an astronomical body moving through space in real
time.  Venus will first encounter the limb of the sun starting
at around 6pm on the east coast, and will take about six hours
to move fully across the sun.

The forecast is for poor weather here, and anyway for us the sun
will set during the transit, but we can watch the whole thing
online at

or

There won't be another Venus transit until 2117, so you might
want to catch this one...
