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 Bulletin 51-2.
  • 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,
  • 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)..."

We report on the results of photometric analysis of two near-Earth asteroids (NEA) by Asteroids Observers (OBAS). This work is part of the Minor Planet Photometric Database (MPPD) project initiated by a group of Spanish amateur astronomers. We have managed to obtain a number of accurate and complete lightcurves as well as some additional incomplete lightcurves to help analysis at future oppositions.

CCD observations of two main-belt asteroids were made in 2016 March and May. Analysis of the data for 4931 Tomsk indicates a synodic period of P = 7.02 ± 0.01 h, A = 0.46 ± 0.10 mag. For 5232 Jordaens, the analysis indicates a synodic period of P = 10.58 ± 0.01 h, A = 0.73 ± 0.15 mag.

Analysis of CCD photometric observations of the near- Earth asteroid (331471) 1984 QY1 show that it is likely in non-principal axis rotation (NPAR), or tumbling. A single period analysis found a dominant period of 45.5 ± 0.5 h, but the true periods of rotation and precession could not be determined.

From 2015 December 12 to 2016 April 16, CCD images were taken with the goal of analyzing the photometric data on twenty-five asteroids: 507 Laodica, 1311 Knopfia, 1363 Herberta, 1454 Kalevala, 1480 Aunus, 1597 Laugier, 1714 Sy, 1791 Patsayev, 1911 Schubart, 2087 Kochera, 2179 Platzeck, 2660 Wasserman, 2828 Iku-Turso, 2854 Rawson, 3228 Pire, 3606 Pohjola, 3669 Vertinskij, 3812 Lidaksum, 3829 Gunma, 3840 Mimistrobell, 4640 Hara, 7016 Conandoyle, 8045 Kamiyama, (12551) 1998 QQ39, and (13388) 1999 AE6.

The B-V and V-R Color Indices on the Surface of NEA (214088) 2004 JN13

2016MPBu...43..290C    Download PDF

This paper presents the results of photometric observations with standard broad-band Bessel filters B, V, and R on near-Earth asteroid (214088) 2004 JN13. The analysis shows that the B-V and V-R color indices are fairly constant on the asteroid surface with mean values B-V = 0.83 ± 0.02 mag and V-R = 0.48 ± 0.03 mag, indicative of a relatively homogeneous surface color distribution. For a typical albedo, assuming these colors indicate an S-type asteroid, a mean diameter of 2.4 ± 0.5 km is inferred.

Synodic rotation periods and amplitudes are found for 124 Alkeste: P = 9.906 ± 0.001 h, A = 0.18-0.29 mag; 465 Alekto: P = 10.936 ± 0.001 h, A = 0.14-0.16 mag; and 569 Misa: P = 11.595 ± 0.001 h, A = 0.09 ± 0.01 mag. Changes in the shapes of the lightcurves in an interval of 40 to 60 days are documented. For 124 Alkeste, V-R = 0.49 and H = 8.155 ± 0.018, G = 0.137 ± 0.019.

Asteroid Lightcurve Analysis at CS3-Palmer Divide Station: 2016 April-July

2016MPBu...43..300W    Download PDF

Lightcurves for nine main-belt asteroids were obtained at the Center for Solar System Studies-Palmer Divide Station (CS3-PDS) from 2016 April to July. Of the group, four are known Hungaria binary asteroids: 1727 Mette, 2047 Smetana, 5899 Jedicke, and (18890) 2000 EV26. The Mars-crosser (54697) 2001 FA70 appears to be a newly-confirmed binary with P1 = 2.7075 h and POrb = 16.269 h. A third period, P2 = 2.1239 h, appears to be real. If so, it could be due to the asynchronous rotation of the satellite or a third body in the system.

Both 50 Virginia and 58 Concordia have irregular lightcurves.

Three Additional Candidates for the Group of Very Wide Binary Asteroids
Pages 306-309
Warner, Brian D.
2016MPBu...43..306W    Download PDF

The very wide binary asteroids (VWBA) are a subgroup of binary asteroids that exhibit very long primary periods and, mostly, short secondary periods that are similar to those of the primary of “normal” small binary asteroids. It is unlikely that confirming mutual events will be seen by photometric observations, mostly because the orbital periods of the assumed satellites will be on the order of days. This paper introduces three additional candidates for this subgroup: (215442) 2002 MQ3, 2009 EC, and 2016 BU13. All three are considered to be among the more convincing examples that such systems exist.

Observations of four main-belt asteroids (MBA) revealed the following rotation periods and lightcurve amplitudes: 3861 Lorenz, P = 11.91 ± 0.01 h, A = 0.28 mag; 6173 Jimwestphal P = 2.908 ± 0.001 h, A = 0.41 mag; 10259 Osipovyurij, P = 6.356 ± 0.001 h, A = 0.30 mag; 29470 Higgs, P = 36.31 ± 0.01 h, A = 0.48 mag.

We present nine nights of photometric observations of the main-belt asteroid 4962 Vecherka. Its amplitude during our observations was not less than 1.08 ± 0.02 mag. We estimated its synodic rotation period at 14 ± 2 d (336 ± 48 h), meaning that 4962 Vecherka is probably among a rare class of slowly rotating, highamplitude asteroids. A much longer observational campaign is required to calculate the period of rotation with a satisfactory accuracy.

Jovian Trojan asteroids larger than ~ 30 km were studied from the Center for Solar System Studies (CS3, MPC U81). Lightcurves for 30 Trojan asteroids in the L4 (Greek) cloud were between May and June 2016. These were mostly from the L4 “Greek” cloud, but several were L5 “Trojan” cloud lightcurves not previously published.

Analysis of CCD photometric observations of near-Earth asteroid (154244) 2002 KL6 indicate that it may be a binary system. The presumed primary has a synodic rotation period of 4.60869 ± 0.00005 h and lightcurve amplitude of 0.65 ± 0.03 mag. The presumed satellite has an orbital period of 24.05 ± 0.02 h and maximum lightcurve amplitude of 0.07 mag. The secondary lightcurve showed no mutual events and seems to indicate that the satellite’s rotation is tidally locked to its orbital period.

The asteroid 2656 Evenkia was observed between 2016 March 20 and April 30. A synodic period of rotation of P = 7.0870 ± 0.0002 h and amplitude of A = 0.68 mag was found.

Initial observations of 2242 Balaton indicated a rotation period of about 2.8 hours with some attenuation events. Further observations and analysis showed that 2242 is a binary asteroid with a primary period of 2.7979 ± 0.0001 h and amplitude of 0.18 mag; the orbital period of the secondary is 12.96 ± 0.01 h. Mutual events that are 0.03 to 0.08 magnitude deep indicate a lower limit on the secondary-to-primary mean-diameter ratio of 0.25. From sparse photometric data we also derived H = 13.31 ± 0.05, G = 0.22 ± 0.04.

Photometric observations of the main-belt asteroids 5318 Dientzenhofer and 9083 Ramboehm were made in 2016 March and 2015 December, respectively. Analysis of the data found a bimodal lightcurve with a synodic rotation period of 8.062 ± 0.002 h for 5318 Dientzenhofer. A trimodal lightcurve with synodic period of 10.199 ± 0.004 h for 9083 Ramboehm was found to be the most likely solution.

Asteroid campaigns to be conducted by the Target Asteroids! program during the October-December 2016 quarter are described. In addition to asteroids on the original Target Asteroids! list of easily accessible spacecraft targets, an effort has been made to identify other asteroids that are 1) brighter and easier to observe for small telescope users and 2) analogous to (101955) Bennu and (162173) Ryugu, targets of the OSIRIS-REx and Hayabusa-2 sample return missions.

We present lists of asteroid photometry opportunities for objects reaching a favorable apparition and having either none or poorly-defined lightcurve parameters. Additional data on these objects will help with shape and spin axis modeling via lightcurve inversion. We also include lists of objects that will be the target of radar observations. Lightcurves for these objects can help constrain pole solutions and/or remove rotation period ambiguities that might not come from using radar data alone.
