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.

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.

An Observing Program for the Serious Amateur
Pages 11-12
McConnell, Mark
1974MPBu....2...11M    Download PDF

Up until a few years ago the asteroids were a commonly neglected group of celestial objects suitable for amateur observing and a steady program of observation was carried out only by professionals and a small group of unorganized amateurs. Now, through the efforts of Dr. J. U. Gunter and, more recently, by the A.L.P.O. Minor Planets Section, this has all changed. It is in conforming to this change that I have written this article as a basic guide to those wishing to make tracking the minor planets their main observing program, as I have done.

Minor Planets at Highly Favorable Opposition in 1975
Pages 13-14
Pilcher, Frederick
1974MPBu....2...13P    Download PDF

The following minor planets will be much brighter than usual at their 1975 oppositions. Observers are encouraged to note any that lie near the ljntit of their equipment, whether it be visual, photographic, or photoelectric. These planets should certain be observed at the current apparition; many years may pass before the next opportunity for observation.

Occultation of Kappa Geminorum by Eros
Pages 14-15
Dunham, David W.
1974MPBu....2...14D    Download PDF

J. Meeus, Erps-Kwerps, Belgium, and M. Gaven, Worcester Park, England, have pointed out that the 3.7-magnitude star Kappa Geminorum (Z.C.1170, spectral type G5) will be occulted by the minor planet 433 Eros on 19?5 January 24.02 U.T.

Minor Planets Passing through Variable Star Fields
Pages 15-16
Hodgson, Richard G.
1974MPBu....2...15H    Download PDF

Observers lacking photoelectric photometry capability may wish to search for and observe minor planets which have sufficiently large light variations (about 0.,4 magnitude or more) to be studied by means of visual variable star methods.

The Densities of Pallas and Vesta and their Implications
Pages 17-20
Hodgson, Richard G.
1974MPBu....2...17H    Download PDF

Recent mass and diameter determinations indicate a density of about 3,0 grams/em for 2 Pallas, suggesting a silicaceous interior, and about 2.0 grams/cm3 for 4 Vesta, indicating possibly an interior consisting of a mixture of silicaceous rock and water ice. Differences in their perihelic distances from the Sun and albedos may be responsible for the density difference between the two planets.

The Rotation Period of 18 Melpomene
Pages 20-21
Welch, Douglas; Binzel, Richard; Patterson, Joe
1974MPBu....2...20W    Download PDF

The results of photoelectric observations of minor planet 18 Melpomene are briefly reported. The period of rotation is found to be 11h 50m, exactly five-sixths of the formerly reported value.
