The #asteroid discoveries during the commissioning of the #Rubin Observatory - 343,760 observations under station code X05, corresponding to 2103 unique objects, were submitted of which 2096 were indeed unknown, including 5 #NEOs - explained in great detail in https://minorplanetcenter.net/media/newsletters/MPC_Newsletter_Jun2025.pdf on pages 1-5.

I wonder about the influence of employment, as well. If you're at risk every work day, I could well imagine it seeming pointless to start being careful the rest of the time, and maybe just too cognitively dissonant to consider.
I remember in 2020, someone I knew was working at Waterstones, and they were forbidden to mask up at work - even though 2020 was before the whole "covid is over" thing.
I also remember reading about someone - maybe a nurse? that _kind_ of job, anyway - who'd started wearing a fitted mask while the default in their workplace was baggy blues, and iirc was formally rebuked. It wasn't allowed.
If for whatever reason you're unable to hold down a typical job, you might not have much cash for _getting_ things like masks, but you're also not under that same kind of economic pressure to put yourself at risk.

Faced with the growing risk that #LightPollution represents for the development of astronomy in Chile, international observatories with a presence in the country have formed a joint organization dedicated to protecting the dark skies of northern Chile: https://giantmagellan.org/2025/06/03/dark-skies-council-international-astronomical-observatories-join-forces-to-protect-chiles-skies/ - the Association of Universities for Research in Astronomy (AURA), the Giant Magellan Telescope, the European Southern Observatory (ESO) and Carnegie Science’s Las Campanas Observatory (LCO), signed an agreement to create the Dark Skies Council; through this alliance, the institutions will work in a coordinated manner to protect Chile’s privileged skies.

The Growing Impact of Unintended #Starlink Broadband Emission on Radio Astronomy in the SKA-Low Frequency Range: https://arxiv.org/abs/2506.02831 -> "We report 112,534 individual detections of 1,806 unique Starlink satellites, some emitting broadband emission and others narrowband emission. [...] It is shown that in the worst cases, some datasets have a detectable Starlink satellite in ~30% of all images acquired. Emission from Starlink satellites is detected in primary and secondary frequency ranges protected by the International Telecommunication Union".
