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:

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.

Amateur Observing by the A. L. P. O. Minor Planets Section
Pages 35-36
Pilcher, Frederick
1985MPBu...12...35P    Download PDF

For many decades hardly any amateur astronomers observed minor planets due to alleged difficulties of distinguishing them from field stars. The availability of the Vehrenberg photographic star atlases eliminated this problem to magnitude 13 or 14, and In the late 1960's enabled several amateur astronomers independently to Initiate asteroid observing programs. Of these I especially praise two.

Photoelectric Studies of Asteroids: The Amateur Contribution

High school students at Globe High School in Globe, Arizona are currently involved in a program of photoelectric photometry of asteroids which has yielded a considerable volume of important information as to the rotational rates and surface properties of 25 bright asteroids.

Careful readers will have noticed that the masthead on the first page of this issue lists it as Ěpart I" of Volume 12, Number 4. Part 2 will be a comprehensive index of the 11inor Planet Bulletin for Volumes 1-12 covering the years of 1973-1985. This extremely useful resource Is being compiled by Clifford Cunningham. This index will be completed in the near future and will be mailed with issue 13-1 In late 1985. Iknow that all readers will join me In thanking Hr. Cunningham for undertaking this monumental task.

Photoelectric Photometry of Asteroid 4 Vesta

Photoelectric photometry for asteroid 4 Vesta was made from North Valley Stream Observatory during the nights of April 28 and 30, 1985. Vesta's rotational period has been previously reported as either 5 hours zo minutes or 10 hours 40 minutes. The data presented here favor the longer period, but not conclusively. The amplitudes observed on April 28 and 30 were 0.11 ▒ 0.01 and 0.14 ▒ 0.02 magnitudes, respectively.

Photoelectric Photometry Opportunities": "Nov. -Jan. 1986"

The table below lists asteroids which come to opposition during the months of November, 1985- January, 1986 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.

Through the August batch of Minor Planet Circulars (MPCs), 43 asteroids were newly numbered, bringing the total past the 3300 milestone to 3302.

Low Phase Angle Asteroids

Based on recent correspondence. now appears to be a good time to repeat the reasons for this quarterly list. Asteroids that pass through very low phase angles undergo a strong surge in brightness known as the opposition effect. The reason or reasons for the opposition effect are still being debated.
