Photometric observations of six asteroids were made from 2015 March to May. We report the results of our lightcurve analysis for 425 Cornelia, 625 Xenia, 664 Judith, 785 Bredichina, 910 Anneliese, and 1831 Nicholson.

The lightcurve of 13003 Dickbeasley was determined using five nights of data from 2015 April and May, from which we found its rotation period to be 3.502 ± 0.0005 hrs. Images were taken at the Phillips Academy Observatory.

These are the first photometric observations ever reported for 2020 Ukko. We find a rotational amplitude of 0.24 ± 0.02 magnitudes and prefer a period of 25.478 ± 0.002 hours with a symmetric bimodal lightcurve. However, periods of 12.733 ± 0.001 hours with a monomodal lightcurve and 38.154 ± 0.002 hours with a trimodal lightcurve fit the data almost as well.

Synodic rotation periods and amplitudes are found for 318 Magdalena (42.49 ± 0.001 hours, 0.06 ± 0.01 magnitudes) and 335 Roberta (12.028 ± 0.001 hours, 0.14 ± 0.01 magnitudes).

Lightcurve analysis using MPO Canopus from two nights of observation of 1238 Predappia found a possible rotation period of 6.13 ± 0.04 h and lightcurve amplitude of 0.05 mag. Low lightcurve amplitude and period spectrum analysis did not provide enough evidence to confirm this rotation period. There are three possible conclusions to gather from these data: Predappia may have a nearly spherical shape, long rotation period, or pole-on orientation during the observation period.

Asteroid campaigns to be conducted by the Target Asteroids! program during the 2015 October-December 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) 1999 JU3, targets of the OSIRISREx and Hayabusa-2 sample return missions.

Photometric observations of main-belt asteroid (16813) 1997 UT6 were made over two nights during 2015 March and April. Observations were obtained remotely at iTelescope Observatory H06 in Mayhill, New Mexico. Analysis of the CCD data found several possible periods. The most likely period is 8.2934 ± 0.0035 h with an alternate period of 7.88 ± 0.003 h.

Initial observations of 3841 Dicicco indicated a period of 3.6 hours with three nights being anomalously low over part of the period. Further analysis showed that 3841 is a binary asteroid with a primary period of 3.5950 ± 0.0001 h with an amplitude of 0.19 mag and a secondary period of 21.641 ± 0.002 h with an amplitude of 0.19 mag. Both the primary eclipse and secondary eclipses were visible. We also estimate the H and G parameters to be H = 13.63 ± 0.04, G = 0.15 ± 0.05.

Lightcurve analysis for 910 Anneliese was performed using observations during its 2015 opposition. The synodic rotation period was found to be 11.2863 ± 0.0002 h and the lightcurve amplitude was 0.16 ± 0.02 mag; the absolute magnitude was HR = 9.974 ± 0.028 mag and the slope parameter was G = 0.107 ± 0.030. These lead to an estimated diameter of 46.3 ± 3.5 km.

Lightcurve Analysis of the Near-Earth Asteroid (6053) 1993 BW3

CCD photometric observations of the near-Earth asteroid (6053) 1993 BW3 were made at the Center for Solar System Studies-Palmer Divide Station (CS3-PDS) in 2015 January and March. Analysis of the individual and combined data sets produced a period on the order of 2.8 hours. This differs significantly from the results of Pravec et al. (1997; P = 2.573 h) and from shape models by Durech (2002) and Kaasalainen (2002). While this discordance is not resolved, the 2.573 h value has the greatest amount of data supporting it, and for now, remains the favored period solution.

Lightcurves for 29 main-belt asteroids were obtained at the Center for Solar System Studies-Palmer Divide Station (CS3-PDS) from 2015 March-June. All but three were members of the Hungaria orbital group or collisional family and observed as part of an ongoing program to obtain data for spin axis and shape modeling. One Hungaria, (79472) 1998 AX4 showed signs of having a satellite. Analysis indicates it is a possible binary.

Photometric observations of the main-belt asteroid 2641 Lipschutz performed by the authors from Italy in 2015 April revealed a bimodal lightcurve phased to 21.62 ± 0.03 hours as the most likely solution resulting from the synodic rotation rate for the asteroid.

CCD photometric observations of 1754 Cunningham, and 7023 Heiankyo were obtained from the Center for Solar System Studies from 2015 June to July. For 1754, the period of 7.7416 ± 0.0005 hours appears to be about twice the previously reported value. For 7023, our solution of 10.807 ± 0.002 hours matches one previously noted possible solution.

Photometric observations of the main-belt asteroids 1492 Oppolzer and (9773) 1993 MG1 were performed by the authors in 2015 April-July. Analysis of the data revealed bimodal lightcurves for each object. For 1492 Oppolzer, we found a synodic period of P = 3.770 ± 0.001 h; for (9773) 1993 MG1, we found P = 2.746 ± 0.001 h.

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.
