CCD photometric observations of four main-belt and one near-Earth asteroid were made in 2019. Of these, the Vestoid 2602 Moore and Hungaria (27568) 2000 PT6 were confirmed to be binary asteroids. The Hungaria 3880 Kaiserman is a suspected binary. Near-Earth asteroid (142040) 2002 QE15 was found to have a long period (46.4 h). Re-evaluation of data for the asteroid from two previous apparitions found a secondary period that is consistent with the system being a candidate for the rare class of very wide binary asteroids. New analysis of the data from 2016 for Phocaea member 2937 Gibbs found two periods (the second being ambiguous). It could not be determined if the asteroid is binary or in a tumbling state.
2019年对四颗主带小行星和一颗近地小行星进行了电荷耦合器件（CCD）光度观测。其中，类灶神星族小行星2602摩尔和匈牙利小行星（27568）2000 PT6被确认为双小行星。匈牙利小行星3880凯泽曼疑似为双小行星。近地小行星（142040）2002 QE15被发现有一个长周期（46.4小时）。对该小行星前两次出现的数据重新评估发现了一个次周期，这与该系统作为罕见的极宽双小行星类候选者相一致。对2016年福基厄族成员2937吉布斯的数据进行的新分析发现了两个周期（第二个周期不明确）。无法确定该小行星是双小行星还是处于翻滚状态。
