This Week's Sky at a Glance
by Alan M. MacRobert
Some daily events in the changing sky for April 9 – 17.
Friday, April 9
Mercury remains to the right of Venus at dusk, but see how it has faded! Mercury is now swinging between us and the Sun and consequently, in a telescope, it's becoming a thinner little crescent. See article.
Saturday, April 10
A small telescope will always show Titan, Saturn's largest moon. Tonight and tomorrow Titan is four ring-lengths to Saturn's east. A 6-inch telescope will begin to show the orange color of its smoggy atmosphere. A guide to identifying other Saturnian satellites often visible in amateur scopes is in the April Sky & Telescope, page 47.
At dawn Sunday morning, look for the waning crescent Moon low in the east. Look about 5° below it for Jupiter (seen from North America), as shown below.
