Vesta

Vesta is nearing opposition. This year it is favorable for viewing since this happens when the asteroid is close to perihelion. It has brightened to naked eye visibility from a dark site. I am not so lucky so I had to attempt to find it with binoculars. It is easy to find, just above Jupiter between the two stars forming the base of Ophiuchus EtaOph and ZetOph, near BS6235, a +6.03 star. This is only the second asteroid I have observed after having seen Iris last November. This asteroid has a special significance to me since I had my name included on a microchip, together with 360,000 others, that will be sent on Nasa's Dawn mission to Vesta and Ceres which is scheduled to launch this summer.
