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 Bulletin51-2.
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.
The asteroid 523 Ada was observed on 4 different nights in 1996 February and March. The best synodic period derived from all these observations is 9.800 ± 0.002 hours with an instrumental V magnitude amplitude of 0.65 -0.70.
The Lightcurve and Period of the Minor Planet 193 Ambrosia
The minor planet 193 Ambrosia is found to have a photometric rotation period of 0.27420 ±0.00025 days (6.5807 ± 0.006 hours) and an amplitude in the Kron-Cousins I band of 0.532 ± 0.013 mag.
Photometric Observations of Minor Planet 212 Medea
CCD photometry of asteroid 212 Medea was performed in April 1996 to determine its rotational period and lightcurve amplitude. The period was found to be 10.25 ± 0.07 hours and the amplitude was 0.11 magnitudes.
The Lightcurve and Period of the C-type Minor Planet 38 Leda
The minor planet 38 Leda is found to have a photometric (rotation) period of 0.5349 ± 0.0018 days (12.84 ± 0.04 hours) and an amplitude in the Kron-Cousins I-band of 0.155 ± 0.024 magn.
Through the July 30 batch of Minor Planet Circulars, 258 asteroids were newly numbered, breaking the 7000 level, and bringing the numbered total to 7100.
Asteroid Photometry Opportunities: November-January
The table below lists asteroids that come to opposition during the months of November through January that represent useful targets for photoelectric or CCD photometry observations. Observations are typically needed because the asteroid has either an unknown or ambiguous rotational period. The table gives (in order of opposition dates) the asteroid number and name, opposition date, opposition V magnitude, the rotational period (in hours), the estimated lightcurve amplitude (in magnitudes), and the designation PER if observations are needed to determine the rotational period. AMB implies that previous period determinations have given ambiguous results and these alternate periods are listed in the table. RAD indicates the asteroid is a planned radar target, and MOD denotes an asteroid at a critical longitude for shape and pole modeling. Question marks are used to denote uncertain or unknown values.
