Asteroid (4) Vesta , mag 5.6 , will occult the star TYC 5641-00161-1, mag 10.9, at 23:33 UT, 17 May 2007. The event is visible from Africa and SW Asia.
The best way to confirm that you have spotted Vesta is to make a quick sketch of the surrounding starfield; then return a few hours, or day later and check to see which one of the `stars` moved...
Mention our solar system and most people conjure up images of the sun, the planets and their attendant moons. But what about the asteroids? Poor li'l asteroids - they seldom get much attention at all. Too bad, too. There may be more asteroids than anything else orbiting our sun. Most tend to lie in the void between Mars and Jupiter and range in size from tiny pebbles to chunks of rock as large as mountains. Only a few are larger than that and can be seen with backyard telescopes. And once in awhile, one becomes bright enough to spot with the unaided eye. Its name is Vesta, and this is a great week to check it out.
Neptune was at the opposite side of the Sun on Feb. 8th, and on May 13th, it will be at west quadrature - 90 degrees west of the Sun. The planet is 30.0807 AU away from us at mid-month. To observe the planet look to the southeast an hour before sunrise. Neptune is located 3 degrees northeast of the star Iota Capricorn. The planet can be observed through binoculars, but a medium-sized telescope (200-300mm) is needed to discern the planets blue disc. A Last Quarter Moon passes just a few degrees from the planet on May 10.

The planet Mars moves through three constellations this month The Red planet starts the month in the constellation Aquarius, then moves into Pisces on the 8th. Between the 24th and 29th the planet is in the constellation Cetus, the Whale. It then moves back into Pisces again. Mars is in the dawn skies, low-down in the south-eastern. Start observing about two hours before sunrise. The brightening skies will drown out the planets light. Through a telescope, the first magnitude planet is disappointingly small and faint. By late December, it will be four times brighter, at magnitude -1.6. The waning crescent Moon sits above and to the left of the planet on May 13th.
