    We present the analysis of stellar binary microlensing event OGLE-2015-BLG-0060 based on observations obtained from 13 different telescopes. Intensive coverage of the anomalous parts of the light curve was achieved by automated follow-up observations from the robotic telescopes of the Las Cumbres Observatory. We show that, for the first time, all main features of an anomalous microlensing event are well covered by follow-up data, allowing us to estimate the physical parameters of the lens. The strong detection of second-order effects in the event light curve necessitates the inclusion of longer-baseline survey data in order to constrain the parallax vector. We find that the event was most likely caused by a stellar binary-lens with masses M = 0.87 pm 0.12 mathrm{M} and M = 0.77 pm 0.11 mathrm{M}. The distance to the lensing system is 6.41 ± 0.14 kpc and the projected separation between the two components is 13.85 ± 0.16 au. Alternative interpretations are also considered.

    Home drinking practices among middle-class adults in midlife during the COVID-19 pandemic: Material ubiquity, automatic routines and embodied states.

    INTRODUCTION: Harmful drinking is increasing among mid-life adults. Using social practice theory, this research investigated the knowledge, actions, materials, places and temporalities that comprise home drinking practices among middle-class adults (40-65 years) in Aotearoa New Zealand during 2021-2022 and post the COVID-19 pandemic lockdowns. METHODS: Nine friendship groups (N = 45; 26 females, 19 males from various life stages and ethnicities) discussed their drinking practices. A subset of 10 participants (8 female, 2 male) shared digital content (photos, screenshots) about alcohol and drinking over 2 weeks, which they subsequently discussed in an individual interview. Group and interview transcripts were thematically analysed using the digital content to inform the analysis. RESULTS: Three themes were identified around home drinking practices, namely: (i) alcohol objects as everywhere, embedded throughout spaces and places in the home; (ii) drinking practices as habitual, automatic and conditioned to mundane everyday domestic chores, routines and times; and (iii) drinking practices intentionally used by participants to achieve desired embodied states to manage feelings linked to domestic and everyday routines. DISCUSSION AND CONCLUSIONS: Alcohol was normalised and everywhere within the homes of these midlife adults. Alcohol-related objects and products had their own agency, being entangled with domestic routines and activities, affecting drinking in both automatic and intentional ways. Developing alcohol policy that would change its ubiquitous and ordinary status, and the 'automatic' nature of many drinking practices, is needed. This includes restricting marketing and availability to disrupt the acceptability and normalisation of alcohol in the everyday domestic lives of adults at midlife.
