LYCOS RETRIEVER 
3 Juno
built 184 days ago
Images of asteroid 3 Juno taken with the 100-inch Hooker telescope at Mt. Wilson Observatory show what appears to be a 60-mile-wide crater. The crater is visible as a darkened area in the lower left quadrant in the 833 nm and 934 nm images. The material excavated by the collision that produced the crater "bite" has low reflectance, especially at the wavelength of 934 nm. An adaptive optics system provided a remarkably clear view of Juno's surface by reducing interference from the Earth's atmosphere. (Sallie Baliunas et al.)

Thirteen lightcurves of asteroid 3 Juno from three different oppositions are given. The pole of Juno is less than 10 deg from ecliptic longitude 104 deg and latitude + 36 deg (or 316 and + 62 deg). The sidereal period is 0.3003969 + or - 0.0000003 (1 sigma) day and the rotation is prograde. There is little similarity between the Juno lightcurves from 8 oppositions which is unexplained at this time.

Factoids: Asteroid 3 Juno was discovered by Karl L. Harding on September 1, 1804. It is one of the largest main belt asteroids and is 'S-Type', which means it is composed of nickel-iron, iron, and magnesium silicates, and is highly reflective. Imaging from the Hooker Telescope in 2003 reveals that Juno has an irregular, potato-like shape, and possesses a 100 km diameter crater that occurred relatively recently. Spectroscopic analysis suggests that Juno could be the source of stony meteorites known as chondrites which are composed of olivine and pyroxene.

The Juno Beach Centre is a museum and cultural centre, which opened at Courseulles-sur-Mer, France on June 6, 2003. The Centre presents the war effort made by all Canadians, civilian and military alike, both at home and on the various fronts during the Second World War, as well as the manifold faces of contemporary Canadian society.

The second race saw Tony take the wheel of the #3 Juno for the whole race; this was Tony’s first time in the Juno and a return to racing after a year. It certainly whetted his appetite and despite an electrical problem ending his second race early he was all smiles in the paddock afterwards. “The Juno is wonderful to drive” he confirmed. “It really is a ‘grown ups’ car. Ewan has done a great job and the team are very welcoming and obviously passionate.”

In the night of May 24/25, 2000 a 9.5 mag star TYC 5212-00753-1 = SAO 145458 will be occulted by a large 267 km asteroid (3) Juno. This update is based on USNO/Flagstaff, TMO and Hipparcos astrometry for the asteroid and Tycho-2 star position.
