Today’s Astronomical Events – May 19th, 2015

Here’s a challenging opportunity for observers across the world tonight as the day old Moon may be visible for a short time after sunset. You’ll stand the best chance if you live in Australia or North America as those in the United Kingdom will only have a small window of opportunity before it sinks below the western horizon.

First find Venus and then look lower, toward the west or north-west (depending upon your location) – the Moon will appear as a thin silver sliver in the twilight. Using binoculars will certainly help.
