Authors Guide and Word Templates   (v.2.9: updated 2019 November 14)
The ZIP file contains the Authors Guide PDF as well as a "starter" paper in Word 97 (DOT) and Word 2007+ (DOTX).
Please read this updated guide since there are a number of changes from previous guides.
  • The Pts column is no longer required and has been removed from the template for the standard table
    to allow more room for the other columns.
  • The phase column should have only two values: for the first and last date in the range.
    If the phase reaches an extrema between those dates, put an asterisk before the first value. For example,
  • Use semicolons to separate names in the references section. For example:
       Smith, J.J.; Jones, A.A. (2019).
    This also applies if using several references to the same author in the text. For example:
    "This asteroid was observed at three previous apparitions (Jones, 2015; 2017; 2018)..."

For 6349 Acapulco, we find typical colors for a C-type asteroid of B-V = 0.7 ± 0.1 mag and V-R = 0.3 ± 0.1 mag and little evidence for color changes as a function of time. We report a rotation period of 4.48 ± 0.05 h that is in good agreement with a previous measurement, and a variability amplitude of 0.55 ± 0.02 mag that is three times larger than previously reported.

Lightcurve Photometry Opportunities: 2022 October-December
Pages 350-354
Warner, Brian D.; Harris, Alan W.; Durech, Josef; Benner, Lance A.M.

We present lists of asteroid photometry opportunities for objects reaching a favorable apparition and have no or poorly-defined lightcurve parameters. Additional data on these objects will help with shape and spin axis modeling using lightcurve inversion. We have changed the presentation of the “Radar-Optical Opportunities” section to include a list of potential radar targets as well as some that are in critical need of astrometric data and, if found, might also be targets for radar. These can have ephemeris errors on the order of tens to thousands of arcseconds and, despite the current surveys, have not been observed for several years. This makes them a double challenge: first to be found and, second, to determine astrometric positions and photometric properties.
