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.

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)..."

V+B Photoelectric Photometry of Asteroids 121 Hermione, 264 Libussa, and 354
Pages 41-43
Hutton, R. G.
1990MPBu...17...41H    Download PDF

Photoelectric observations of the asteroids 121 Hermione, 264 Libussa and 354 Eleonora were made from Estacion de Altura MEl Leoncito of Felix Aguilar Observatory during the 1989 apparition. The synodic rotational period, lightcurve amplitude and average B-V color found for 121 Hermione are: P = 8.97 ± 0.07 hr., Δm = 0.12 ± 0.01, B-V = 0.699 ± 0.014. For 354 Eleonora the previously reported 4.277 hr. period is confirmed and the observed amplitude and colors are: Δm = 0.16 ± 0.01. B-V = 0.931 ± 0.014. For 264 Libussa the synodic rotational period is not less than 8 hr., with lightcurve amplitude >0.22 mag. and average B-V = 0.838 ± 0.014.

The following precise astrometric positions have been measured from photographs obtained with a Newtonian reflector of 41 em aperture, 1.943 meter focal length, and hypersensitized KODAK TP 2415 film. The location of the observatory is: Longitude 4°12'34" E; Latitude 45°22'50" N; Altitude 448 meters.

I was a bit surprised to find in the current issue of MPB a short article by Floyd Hutson in which he reported residuals between his astrometric observations and positions predicted by my ephemeris program. My program Is Intended only for finding objects, not reducing astrometric observations, as It does not include topocentric or aberration of llght corrections, among others. and some arithmetic Is done In single precision. The 0-C residuals he reported are, If anything, smaller than the errors I would have expected in my computations alone, so it is no surprise that the residuals are larger than his solution error estimates. Indeed, it is entirely possible that his observations, if measured against a higher precision ephemeris, might yield much smaller residuals.

I am attending the Corporation for Research Amateur Astronomy Baja '91 Symposium at La Paz. Mexico, around the time of the solar eclipse July 11, 1991. Here I shall present a paper, The Minor Planets Section of the Association of Lunar and Planetary Observers.· I shall appreciate the support of any Minor Planets Section members who can also attend. Even if you cannot attend the Symposium, please contact me about any of your activities which you wish for me to include. I shall peruse the last 2 years' issues of the Minor Planet Bulletin, plus those to be published up to the time of the Symposium, for as complete a range of our undertakings as I can find.

Oppositions of 944 Hidalgo Revised

Meeus, J.; Goffin, E.
1990MPBu...17...46M    Download PDF

Harris (1990) gives a list of favorable oppositions of minor planet 944 Hidalgo between the years 1900 and 2050. We were rather surprised to read that for this purpose an unperturbed orbit was used, With the statement that the opposition dates •far from the current epoch may be off by a day or so·. This ·current epoch· itself Is not mentioned in the article, and we fear that the author has been too optimistic. Indeed, our Table II shows that, of the 22 opposition dates given by Harris, only five are less than two days in error. For many others, the error amounts to several months, with the consequence that the corresponding data are completely meaningless.

Photoelectric Photometry Opportunities: November-January

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.
