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)..."

Issues for the upcoming quarter-year are released on about the 21st of March, June, September, and December. Full issues and individual papers from vol 1 (1973) to present are available via links on this page.

Important: If the ADS bibcode and "Download PDF" links are missing for the latest issue, it is because the ADS has not processed the files. The links will be made available after the ADS processes the files.
If the "Download PDF" link is visible and there is no PDF available, clicking the link will download an arbitrary page. We are working with ADS to make sure all papers are available and, if not, being able to diasable the link. The "Download Full Issue" link does retrieve the correct file.

Vol 1-7 run Jul-Jun. Vol 8-present run Jan-Dec. Only papers indexed in the ADS are included. Earlier volumes often contain more papers than listed here. It's recommended to download the full issue in vol 1-9.

Interpolating Minor Planet or Comet Positions Between Ephemeris Dates
Pages 23-24
Pilcher, Frederick
1975MPBu....3...23P    Download PDF

Ephemerides are normally printed at 0h Ephemeris Time (ET), that is, for 8 pm Eastern Daylight Time, 7 pm Central Daylight Time, etc. of the preceding day. Ten day intervals are normally used exaept for rapidly moving objects for which the time interval maybe Shorter. To predict a position for a time other than Oh ET on an ephemeris date, the time must first be expressed in days and decimal fractions thereof. With 1440 minutes in a day, every 0.01 day is 14 4 minutgs, or for extreme accuracy every 0.00001 day is 0.864 seconds. In the following example days are expressed to hundredths, right ascension to 0.1m, declination to 1' but the method may be used to any desired level of accuracy.

Visual Photometry lists

Wallentine, Derek; Porter, Alain C.
1975MPBu....3...25W    Download PDF

Four close passages are featured among the visual photamatry opportunities for the last three months of 1975. For all but one of the listed planets there is no knowledge of their lightcurves, so observers of these events could make significant contributions to our knowledge of these bodies.

Minor Planets at Unusually Favorable Opposition in 1976
Pages 29-32
Pilcher, Frederick
1975MPBu....3...29P    Download PDF

A list is presented of 91 minor planets which are much brighter than usual at their 1976 oppositions. Observaticms are especially urged for 1580 Betulia and 944 Hidalgo at their coming close approaches to Earth, and ephemerides are provided.

Planets 1580 Betulia and 1620 Geographos in 1976
Pages 33-34
Meeus, Jean
1975MPBu....3...33M    Download PDF

Almost every year the "recreational celestial mechanics" brings us something new. In 1975 we have the closest approach of Eros of the present century, and later the close Pallas-Vasta conjunction. In 1976, it's the interesting motions of 1580 Betulia and 1620 Geographos which have our attention.
