The goal of this investigation is to determine the origin and surface composition of the asteroid (121514) 1999 UJ7, the only currently known L4 Martian Trojan asteroid. Methods. We have obtained visible reflectance spectra and photometry of 1999 UJ7 and compared the spectroscopic results with the spectra of a number of taxonomic classes and subclasses. A light curve was obtained and analysed to determine the asteroid spin state. Results. The visible spectrum of 1999 UJ7 exhibits a negative slope in the blue region and the presence of a wide and deep absorption feature centred around ∼0.65 µm. The overall morphology of the spectrum seems to suggest a C-complex taxonomy. The photometric behaviour is fairly complex. The light curve shows a primary period of 1.936 d, but this is derived using only a subset of the photometric data.

Work done while supported by an appointment to the NASA Postdoctoral Program, administered by Oak Ridge Associated Universities through a contract with NASA. ^Currently at Lunar and Planetary Laboratory, University of Arizona, Tucson AZ Abstract Asteroids belonging to the Ch spectral taxonomic class are defined by the presence of an absorption near 0.7 μm, which is interpreted as due to Fe-bearing phyllosilicates. Phyllosilicates also cause strong absorptions in the 3-μm region, as do other hydrated and hydroxylated minerals and H2O ice. Over the past decade, spectral observations have revealed different 3-µm band shapes the asteroid population. Although a formal taxonomy is yet to be fully established, the “Pallas-type” spectral group is most consistent with the presence of phyllosilicates. If Ch class and Pallas type are both indicative of phyllosilicates, then all Ch-class asteroids should also be Pallas-type. In order to test this hypothesis, we obtained 42 observations of 36 Ch-class asteroids in the 2- to 4-µm spectral region.

  • A Method for Determining the V Magnitude of Asteroids from CCD Images
    A method for determining the V magnitude of asteroids from CCD images Roger Dymock & Richard Miles A contribution of the Asteroids & Remote Planets Section (Director: Richard Miles) We describe a method of determining the V magnitude of an asteroid using differential photometry, with the magnitudes of comparison stars derived from Carlsberg Meridian Catalogue 14 (CMC14) data. The availability of a large number of suitable CMC14 stars enables a reasonably accurate magnitude (±0.05 mag) to be found without having to resort to more complicated absolute or all-sky photometry. An improvement in accu- racy to ±0.03 mag is possible if an ensemble of several CMC14 stars is used. This method is expected to be less accurate for stars located within ±10° of the galactic equator owing to excessive interstellar reddening and stellar crowding. The problem The CMC14 catalogue The Carlsberg Meridian Telescope (formerly the Carlsberg Differential photometry is fairly straightforward in that all the Automatic Meridian Circle) is dedicated to carrying out high- required data can be obtained from images of the target ob- precision optical astrometry.1 It underwent a major upgrade in ject.
