Comet tonight....

Comet Lulin will be on display throughout the night on February 23-24, starting around mid-evening. Near peak brightness in a moonless sky, Comet Lulin should be fairly easy to spot through binoculars, even in mildly light-polluted skies.

The whole trick to seeing Comet Lulin is to know right where to look. That’s where the bright golden planet Saturn comes in handy. At mid to late evening, look for Comet Lulin to appear as a hazy speck of light to Saturn’s right. In a dark country sky, you might even see Comet Lulin with the unaided eye.

Comet Lulin probably won’t be high enough in the east for decent viewing until 8:30 or 9:00 p.m. Later at night is even better. At mid-evening, two respectively bright starlike points of light bedeck the eastern sky. The higher of these two lights is the star Regulus, the brightest star in the constellation Leo the Lion. Saturn is to the lower left of Regulus, its golden color contrasting to that of sparkling blue-white Regulus. If you can’t distinguish their colors with the unaided eye, try looking at Saturn and Regulus with binoculars.

Comet Lulin and Saturn will remain within each other’s vicinity all night long, until morning dawn finally washes them from the sky. Look for Comet Lulin and Saturn to swing highest up for the night around 1 a.m. on February 24, at which time they’ll be due south. If you’re up before dawn on February 24, look for Comet Lulin and Saturn in your western sky.

Astronomers believe this is Comet Lulin’s first trip into the inner solar system. There’s always an element of unpredictability associated with comets, especially a pristine comet like Comet Lulin. Comet Lulin may match, exceed or fall short of expectations, but there is no way to know for sure unless you look!

If you miss Comet Lulin by Saturn on February 23-24, try again on the night of February 27-28, when Comet Lulin will cozy up with Regulus!
