While this workshop is not being held at the best time of day for
Australian astronomers, it may be of interest to many.
Satellite Constellations 1 Workshop

astronomers Clara Martínez-Vázquez and Cliff Johnson.
The National Science Foundation’s NOIRLab and the AAS, with support from
NSF, are hosting the Satellite Constellations 1 (SATCON1) workshop
virtually from 29 June to 2 July 2020. The first two days are open to
people interested in mitigating the impact of satellite constellations
This workshop will gather together astronomers, satellite operators,
dark-sky advocates, policy-makers, and other stakeholders and interested
parties to discuss, understand, and quantify the impacts of large
satellite constellations on astronomy and the human experience of the
night sky. The goal is to work collectively towards effective solutions
to mitigate those impacts and to publish them in a white paper which
will be widely distributed. As launches and deployments of these
satellite constellations have already begun, and new launches are
planned for every few weeks, time is of the essence.
*i*n the weeks before the workshop, four working groups are drafting a
report summarizing the current state of knowledge in four areas (1)
synthesizing results from ground-based observations of satellites and
identify future observing program needs; (2) examining the current
status of simulations for assessment of impact and need for further
refinement; (3) exploring mitigation through lab measurement of
satellite surface reflection and detector performance as well as
operational strategies; and (4) developing a set of metrics for
protection of Optical/IR observations based on the results of the other
working groups. Their findings will be shared with registered attendees
and other stakeholders in a document a few days before the workshop and
will be presented and discussed during the first two days of the
workshop. Through the outcome of the discussions, revisions will be made
and a white paper will result with recommendations that include
quantitative metrics and an understanding on the impact on the science
as well as our cultural heritage. This white paper will then be widely
*When are the conference dates?*
Days 1 and 2, Monday, 29 June and Tuesday, 30 June, are open to
astronomers, satellite operators, dark-sky advocates, policy-makers, and
other stakeholders. The first two days will be devoted to sharing
results from the four working groups and discussion.
Days 3 and 4, Wednesday, 1 July and Thursday, 2 July, will focus on the
working groups (and highly interested attendees) merging information
from the discussions and the pre-workshop document into produce a final
We will meet for four hours each day, in two 2-hour blocks:

* 10:30am–12:30pm US Eastern Time/Chilean Time and 1:00pm–3:00 pm US
Eastern Time/Chilean Time
* 14:30 – 16:30 UTC and 17:00 – 19:00 UTC
* 16:30 – 18:30 CEST and 19:00 – 21:00 CEST
