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.

Print subscriptions are no longer available to individuals. Institutions (e.g., college libraries) can still obtain print copies via a special subscription. See details in MPB 37-4 or contact the editor, Richard Binzel.

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)..."

Lightcurves of 165 Loreley obtained on three nights in early 2006 can be satisfied by several different rotation periods, one of which, 7.224 hours, is consistent with the tabulated value, with an amplitude of 0.17 mag.

CCD photometry of asteroids 276 Adelheid, 1490 Limpopo, and 2221 Chilton obtained at the Universidad de Monterrey Observatory during August and September 2005 is reported. A synodic rotation period of 6.315±0.005 hours and an amplitude of 0.17±0.03 magnitudes is confirmed for Adelheid from five nights of observations. The resulting synodic rotation period and amplitude for Limpopo is 6.426±0.003 hours and 0.16±0.03 magnitudes from three nights of observations. Chilton was observed on four nights and exhibits a synodic rotation period of 7.445±0.015 hours and an amplitude of 0.20±0.05 magnitudes, though the period is uncertain due to the faintness of the asteroid in the images. Another possible solution for the rotation period of Chilton is 8.63±0.02 hours.

The asteroid (35690) 1999 CT21 was incidentally recorded on 29 and 30 July 2000 UT during the observations of the globular cluster M22. These data have allowed determination of the synodic rotation period to be 9.06 ± 0.02 hours. On 29 July 2000 the reduced V magnitude, the amplitude of the light variation and color index B-V were 14.82 ± 0.01, 0.60 ± 0.02 and 0.7 ± 0.1 mag, respectively. Dimensions and the biaxial ellipsoid models of this asteroid have been obtained for two assumed taxonomic classes (C and S).

Hungaria asteroid 6384 Kervin is found to have a synodic lightcurve period of 3.6203±0.0003hr and amplitude 0.10±0.02mag. The period and size are such that the asteroid was a binary candidate. No signs of mutual events were seen; however, initial runs showed slight, but eventually unsubstantiated, indications of a secondary period. Observations at other viewing aspects are encouraged to rule out a binary nature completely.

The main-belt asteroid, 71 Niobe, was the target of radar observations in early 2006 by Shepard. Supporting optical observations (lightcurve) were requested. Initial optical observations by Warner indicated the previously reported period of 14.38h (Harris 1989a) may have been incorrect. Follow up observations, optical and radar, showed that a synodic period of 35.6±0.1h is more likely correct. The observed amplitude is 0.22±0.02mag.

The lightcurves of 1043 Beate and 1186 Turnera
Pages 104-105
Warner, Brian D.; Higgins, David
2006MPBu...33..104W    Download PDF

Observations of 1043 Beate in April 2006 found the synodic period to be 22.05±0.10hr or, possibly, 44.10±0.10hr. The lightcurve amplitude was 0.32±0.02mag. The synodic period for 1186 Turnera was determined to be 12.066±0.004hr based on observations also obtained in April 2006; its lightcurve amplitude was 0.34±0.02mag. With both having adopted periods nearly commensurate with 24hr, the importance of collaboration among observers at different longitudes was again demonstrated. This was particularly true in the case of 1043 Beate, where combined runs allowed forming a single long run on more than one occasion, and so provided additional clues in finding a solution.

Lightcurve photometry opportunities October - December 2006
Pages 107-109
Warner, Brian D.; Harris, Alan W.; Pravec, Petr; Kaasalainen, Mikko; Benner, Lance A. M.
2006MPBu...33..107W    Download PDF

We present here four lists of “targets of opportunity” for the period 2006 October through 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.
