The Minor Planet Bulletin is the journal for almost all amateurs and even some professionals for publishing asteroid photometry results, including lightcurves, H-G parameters, color indexes, and shape/spin axis models. It is considered to be a refereed journal by the SAO/NASA ADS. All MPB papers are indexed in the ADS.

Please read this updated guide since there are a number of changes from previous guides.
  • A new, optional, table is available for those wanting to include physical and discovery information
    in a more accessible way.
    See the announcement in Minor Planet Bulletin 51-2.
  • 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)..."

Suggested Revised H Values of Selected Asteroids: Report Number 3
Pages 95-99
Faure, Gerard; Garret, Lawrence
2007MPBu...34...95F    Download PDF

We report results obtained by the “Magnitude Alert Project” (MAP) during the first ten years of activity, from 1996 to 2006. As of December 31, 2006 the MAP Database contained 430 asteroids and 4927 measures. 16 minor planets, for which visual and CCD measures indicate an average difference of H magnitude from the current predicted values, have been observed at least during three oppositions. These confirmed discrepancies are from 0.3 to 2.6 magnitudes. We suggest a revision of their catalogued H magnitude to permit better predicted magnitudes in ephemerides of these objects, notably by the Minor Planet Center.

Initial Results of a Dedicated H-G Project
Pages 113-119
Warner, Brian D.
2007MPBu...34..113W    Download PDF

One of the main obstacles to studies of the asteroid population, NEAs in particular, is the lack of good H (absolute magnitude) and G (phase slope) values. Starting in early 2007, the Palmer Divide Observatory began a dedicated program for determining the H-G values for as many asteroids as possible. The initial efforts involved MBA asteroids as a control group where the results were compared to values given in the MPCORB file (MPC 2007). Subsequent observations will concentrate on brighter targets within the NEA and inner main-belt populations. A consequence of these observations is also the determination of the V-R color index for almost all targeted asteroids. This paper discusses the details of the project, from strategy to implementation, as well as reporting some initial findings.

An observing program to search for cometary features among the asteroidal population is presented. No additional instruments other than those normally used for minor planet observations are necessary. The involved observers periodically receive an observing planner by email and the observing results are shared over the internal mailing list. Once confirmed, results are communicated to the professional community.

Lightcurve Photometry Opportunities October-December 2007

We present here four lists of “targets of opportunity” for the period 2007 October-December. The first list is those asteroids reaching a favorable apparition during this period, are <15m at brightest, and have either no or poorly constrained lightcurve parameters. By “favorable” we mean the asteroid is unusually brighter than at other times. In many cases, a favorable apparition may not come again for many years. The goal for these asteroids is to find a well-determined rotation rate, if at all possible. Don’t hesitate to solicit help from other observers at widely spread longitudes should the initial finding for the period indicated that it will be difficult for a single station to find the period.
