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.

Authors Guide and Word Templates   (v.2.9: updated 2019 November 14)
The ZIP file contains the Authors Guide PDF as well as a "starter" paper in Word 97 (DOT) and Word 2007+ (DOTX).
Please read this updated guide since there are a number of changes from previous guides.
  • 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)..."

Space-Rocky Road to Observatory Automation and Lightcurves
Pages 1-3
Fekete, Paula; Porter, Jaxon J.; Willis, Jacob P.

We report six lightcurve analyses based on observations obtained at the West Point Observatory over the interval 2021 September through 2023 February. One notable result is finding a previously unreported rotation period for 4482 Frèrebasile; P = 3.043 ± 0.001 hours with an amplitude of 0.12 magnitudes. Since these are the first asteroid photometry results reported from our Observatory, we also detail some aspects in developing our program and some unique challenges for meshing astronomical projects with the cadet lifestyle.

Lightcurves and rotation periods were found for six asteroids observed from 2021 April to May.

Lightcurves and Derived Results for Koronis Family Member (5139) Rumoi, Including a Discussion of Measurements for Epochs Analysis

Slivan, Stephen M.; Barrera, Kaylee; Colclasure, Abigail M.; Cusson, Erin M.; Larsen, Skylar S.; McLellan-Cassivi, Claire J.; Moulder, Summer A.; Nair, Prajna R.; Namphy, Paola D.; Neto, Orisvaldo S.; Noto, Maurielle I.; Redden, Maya S.; Rhodes, Spencer J.; Youssef, Sandra A.

Lightcurves of (5139) Rumoi recorded during three apparitions are presented, with derived results for synodic rotation period, solar phase coefficients, color index, and absolute magnitude, along with an analysis for spin direction and sidereal rotation period in combination with previously published data. An approach for measuring lightcurves for epochs analyses also is described.

Farfán, Rafael González; de la Cuesta, Faustino García; Carballo, Juan-Luis González; Fernández, José María; Fernández, Javier Ruiz; Reina, Esteban; Podlewska-Gaca, Edyta; de Elias, Javier Cantalapiedra

CCD photometric observations of minor planet 5780 Lafontaine were made in 2023 July and August by a group of observers from Spain and Poland. Analysis of the data could not find a definitive solution for a synodic rotation period.

Lightcurves and Rotation Period Determination of Seven Main-Belt Asteroids Observed from Malta and Slovakia
Pages 12-15
Brincat, Stephen M.; Bucek, Marek; Galdies, Charles; Mifsud, Martin; Grech, Winston

We present the results of our photometric observations of seven main-belt asteroids from five observatories in Malta and Slovakia. We have managed to derive the lightcurves for the following asteroids that can assist future analysis of these objects at different oppositions: (1400) Tirela; (1850) Kohoutek; (2591) Dworetsky; (5163) Vollmayr-Lee; (5606) Muramatsu; (23080) 1999 XH100 and (66875) 1999 VY52.

Photometric Observations of Main-Belt Asteroids 784 Pickeringia, 1465 Autonoma, 1477 Bonsdorffia, 3057 Malaren, 5708 Melancholia, and 8548 Sumizihara
Pages 16-19
Galdies, Charles; Brincat, Stephen M.; Bucek, Marek; Mifsud, Martin

Photometric observations of selected asteroids were done from Znith Observatory, Flarestar Observatory (MPC-171), Luckystar Observatory (MPC-M55), and Manikata Observatory in 2023. The observations were made during a favorable apparition for each asteroid. Some of these targets were never studied in the past and thus their rotation periods were unknown.

Pilcher, Frederick

Synodic rotation periods and amplitudes at their year 2023 oppositions are found for 903 Nealley 29.063 ± 0.006 hours, 0.06 ± 0.01 magnitudes with one maximum and minimum per rotational cycle; 1051 Merope 13.712 ± 0.001 hours, 0.17 ± 0.01 magnitudes with one maximum and minimum per rotational cycle; 1187 Afra 14.071 ± 0.001 hours, 0.68 ± 0.05 magnitudes.

Asteroid Lightcurve Analysis at the Center for Solar System Studies Palmer Divide Station: 2023 July-October
Pages 22-30
Warner, Brian D.

CCD photometric observations of 22 asteroids were made at the Center for Solar System Studies Palmer Divide Station during 2023 July to October. Data analysis found four likely binary asteroids: 7187 Isobe, 20037 Duke, 21149 Kenmitchell, and (53453) 1999 XX135. A review of data from 2018 for 17405 McAdams found a period somewhat near half that found using 2023 data. As standalone solutions, both would seem to be valid.

Lightcurve Photometry Opportunities: 2024 January-March
Pages 83-86
Warner, Brian D.; Harris, Alan W.; Durech, Josef; Benner, Lance A.M.

We present lists of asteroid photometry opportunities for objects reaching a favorable apparition and have no or poorly-defined lightcurve parameters. Additional data on these objects will help with shape and spin axis modeling using lightcurve inversion. We have changed the presentation of the “Radar-Optical Opportunities” section to include a list of potential radar targets as well as some that are in critical need of astrometric data and, if found, might also be targets for radar. These can have ephemeris errors on the order of tens to thousands of arcseconds and, despite the current surveys, have not been observed for several years. This makes them a double challenge: first to be found and, second, to determine astrometric positions and photometric properties.

Warner, Brian D.

This list gives those asteroids in this issue for which physical observations (excluding astrometric only) were made. This includes lightcurves, color index, and H-G determinations, etc. In some cases, no specific results are reported due to a lack of or poor quality data. The page number is for the first page of the paper mentioning the asteroid. EP is the "go to page" value in the electronic version.
