That's right: If local skies are clear, Comet Lulin can be seen by everyone around the world, tonight - just after midnight.
In the Northern Hemisphere, look in the south-southeast sky at 1:00 a.m. In the Southern Hemisphere, look in the north-northwest at 1:00 a.m. Remember, Comet Lulin is traveling 'backward" and it will also be close to the triple-planetary conjunction now lining up.
Unaided "naked eye" viewing will probably see a small, faint patch of gas (next to Saturn) - that's the comet. Help from binoculars or a telescope, however, will allow those with clear skies to see comet details, as well as witness Comet Lulin's actual motion as it moves across the stars.
Only those living on the Pacific Rim, however, will see the quadruple transit of Saturn's four moons (3 a.m., PST).
