Potato-shaped asteroid Vesta will soon be bright enough that you can actually (but barely) see it with unaided eyes, if you are in dark, rural location and have a good star chart. It is easy to see with binoculars, and is in the eastern sky this evening.
Binocular users can watch Vesta gradually move through Leo, passing close to Gamma Leonis on the evenings on February 16 and 17. In fact, it will pass tightly between Gamma and a +5th magnitude star, 40 Leonis.

One of the sky's nicest gifts this month is an easy way to find and track the large asteroid 4 Vesta. This space rock remains within 1 binocular field of the 4th-magnitude star Alpha Piscium, which lies halfway up in the southeastern sky during early evening.
From a suburban backyard, you can spot the 7th-magnitude asteroid without much effort. Apart from Alpha, only three other stars in the area shine brighter than Vesta. From December 7 to 9, Vesta appears near the vertex of an equilateral triangle of these stars, the brightest of which is Alpha itself.

The asteroid Vesta is somewhat shy at 6.4 magnitude. We have a better-than-average chance to add the asteroid notch to our astronomy observing belts this week since Vesta reaches greatest brilliance tonight.
