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.
Please send a check, drawn on a U.S. bank and payable in U.S. funds, to "Minor Planet Bulletin" and send it to:

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,
*7.2,13.7.
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.

Rotation Period and Lightcurve of Asteroid 338 Budrosa
Pages 37-38
Hutton, R. Gil; Licandro, J.
1991MPBu...18...37H Download PDF

Photoelectric observations in V and B filters of the asteroid 338 Budrosa were made from Estaci6n de Altura "Dr. Carlos U. Cesco" of Felix Aguilar Observatory during the 1990 apparition. The synodic rotational period, lightcurve amplitude and average B-V color found for 338 Budrosa are: P = 4.6 ± 0.1 hr. Δm = 0.47±0.0l, B-V = 0.680 ± 0.014. This is the first secure period reported.

Photoelectric Photometry of Asteroid 125 Liberatrix

Photoelectric observations in V and B filters of the asteroid 125 Liberatrix were made from Estaci6n de Altura "Dr. Carlos U. Cesco" of Felix Aguilar Observatory during the 1990 apparition. The 3.97±0.1 hour synodic rotational period, and 0.695±0.014 average B-V color agree with previous determinations. The lightcurve amplitude found is t.m=0.30 ±0.01.

Through the September 23 batch of Minor Planet Circulars, 238 asteroids were newly numbered since the last installment of News Notes, bringing the numbered total to 4960.

Photoelectric Photometry Opportunities: November-January

1991MPBu...18...43H Download PDF

The table below lists asteroids which come to opposition during the months of November through January that 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.
