<p>Dear All,</p>
<p>While this workshop is not being held at the best time of day for
Australian astronomers, it may be of interest to many.</p>
<p>Cheers, Sarah<br>

<p dir="ltr" class="" style="font-family: ArialMT;">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 on astronomy.</p>
<p dir="ltr" class="" style="font-family: ArialMT;">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. </p>
<p class="text-align-center" dir="ltr" style="font-family: ArialMT;"><strong class="">i</strong>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 disseminated. </p>
<p dir="ltr" class="" style="font-family: ArialMT;"><strong class="">When are the conference dates?</strong> </p>
<p dir="ltr" class="" style="font-family: ArialMT;">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.</p>
<div class="" style="font-family: ArialMT;">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 white paper.</div>
