The Minor Planet Bulletin

Click on image to zoom

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.

Annual voluntary contributions of $5.00 or more in support of the publication are welcome.

Authors Guide and Word Templates   (v.3.0: updated 2024 February 2)
The ZIP file contains the Authors Guide PDF as well as a "starter" paper in Word 2007+ (DOTX).
Those using Word 97 (DOC/DOT) are encouraged to download OpenOffice and convert their files to the most recent Word format (DOCX).
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)..."

The Lightcurve and Period of the S Type Minor Planet 198 Ampella
Pages 31-32
De Young, J. A.; Schmidt, R. E.
1993MPBu...20...31D    Download PDF

The minor planet (198) Ampella has its period of lightcurve variation determined to be 10.383 ± 0.001 hours. Three well-defined extrema are evident in the 0.22 ± 0.02 mag. amplitude lightcurve with other low-amplitude, order 0.01 m, structure indicated.

Call for Observations of Asteroid 1620 Geographos

Binzel, R. P.
1993MPBu...20...33B    Download PDF

In January 1994 a small U.S. spacecraft named Clementine will be launched to a lunar orbit. In May 1994, its orbit will be redirected to flyby the asteroid 1620 Geographos on 31 August 1994. The spacecraft payload includes an UV/Visible camera, near-infrared camera, and long wavelength IR camera. Geographos will become the third asteroid encountered and imaged by a spacecraft.

Asteroid Close Approaches

Photoelectric Photometry Opportunities: November-January
Pages 37
Harris, A. W.; Zappalá, V.
1993MPBu...20...37H    Download PDF

The table below lists asteroids that come to opposition during the months of November through January which represent useful targets for photoelectric photometry observations. Observations are needed because the asteroid has either an unknown or ambiguous rotational period or because the asteroid Will be observable at a very low phase angle.
