Dear Supporters of the International Day of Light,
 
Firstly, please let us wish you all, your friends and your families all the best during these challenging times. 
 
Because of the recent outbreak of COVID-19, cities and countries worldwide are putting into place a number of containment measures that seriously impact the organization of conferences and public events. As a result, many activities that have been planned for the International Day of Light 2020 (IDL2020) on May 16 will no longer be able to take place as scheduled. Whilst we appreciate that this will be disappointing, it is essential to prioritize health above all, and we would like to stress to everyone the importance of following all local and national guidelines that are being put into place to safeguard our wellbeing. This newsletter outlines some potential alternatives that you may wish to consider. We also want to emphasize that events for IDL can take place at any time in 2020. Please
contact us to update your event registration in the global calendar.
 
For the 2020 International Day of Light, activities of all kinds are encouraged to facilitate maximum participation, research and impact worldwide. This includes the implementation of events online, which can also bring the advantage of bringing in a larger audience! We are also happy to share and promote your online events, and how to participate in them, across IDL social media. There are various IDL resources available
online, including skilled speakers, videos and activities that you can make use of for your events.
 
Please regularly check the IDL2020 website for updates and news items and continue to reach out to us via Twitter (@
IDLOfficial), Facebook (@DayOfLight2020) and Instagram (@IDL2020) or by email if you have any questions about IDL or you want to share any idea or resources.
 
Despite the ongoing challenges, the International Day of Light presents a special opportunity for us to come together for a common celebration!

Updates for IDL2020 amid COVID-19 Concerns

Because of the recent outbreak of COVID-19, cities and countries worldwide are putting into place a number of containment measures that seriously impact the organization of conferences and public events.  As a result, many activities that have been planned for the International Day of Light 2020 (IDL2020) on May 16 will no longer be able to take place as scheduled. Whilst we appreciate that this will be disappointing, it is essential to prioritize health above all, and we would like to stress to everyone the importance of following all local and national guidelines that are being put into place to safeguard our wellbeing.  

There are, however, some potential alternatives that you may wish to consider:

Firstly, although the International Day of Light recognizes the anniversary of the first laser operation on 16 May, events throughout 2020 can still take place with official recognition as an IDL2020 activity.  And so instead of cancelling outright, at this stage you may wish to simply announce rescheduling to a later date to be confirmed once we see how the global situation evolves. Please contact Bethany Downer to update your event information (such as  dates or event description) on the IDL Events page.

Secondly, many events such as conferences are already responding to the travel restrictions by adopting all-online formats. The next item in the newsletter details some ways to implement a successful online event.

And of course, IDL2020 will continue to be active on Social Media and our regular communication channels.  

The situation we are in at this time is unique, and we are all learning together how to adjust and reorganize our work and lives. Please contact the International Day of Light secretariat if you have any questions. And of course, please take all precautions to stay healthy during this challenging time. 


How to Organize an Online Event for IDL2020
 
For the 2020 International Day of Light, activities of all kinds are encouraged to facilitate maximum participation, research and impact worldwide. This includes the implementation of events online.

A great example of an effective event conducted by distance was the inaugural Photonics Online Meetup (POM) in January, which brought together over 1100 researchers to discuss the latest advances in photonics. This meeting was completely delocalized with speakers, organizers, and attendees scattered across six continents and hundreds of locations, connected via a video-conferencing tool and social media. The infrastructure (communication, video platform, website and advertisement), program, challenges and successes of this event are explored in depth in this paper by O. Reshef et al in a recent publication in Nature Materials. This paper highlights not only how to successfully conduct a large-scale event of this nature online, but also considers some impact factors that may be unique to web-type gatherings. For example, the event’s virtual poster session was held entirely on Twitter via a specially designed poster format. It featured 60 high-quality posters that yielded an average of 3,000+ impressions recorded per poster in the first three days – quite an impressive feat that is arguably more impactful in terms of engagement than an in-person conference.

If you are interested in conducting an event online, we encourage you to explore the variety of resources on the IDL website to support your activities. This article highlights the many ways you can make use of the IDL visuals and banners, speakers, videos and ideas. A Quick Guide to organizing an IDL event has also been established make activity implementation easier for your planned celebrations this year. Furthermore, a special tagline and campaign for communications and outreach of the 2020 IDL activities was established called See The Light, to connect all of our celebrations with one voice that reaches the public. Another way to interact with other IDL events online is to follow and engage with the official IDL social media channels using the hashtag #IDL2020 and the official channels: @IDLOfficial on Twitter and @DayOfLight2020 on Facebook. 
OPTIQUE Dijon 2020:  Venez à Dijon

From 7-10 July 2020, Dijon will be the showcase for the flagship congress of the French Optical Society SFO, which will highlight the diversity and vigour of all optical sectors in France. OPTIQUE Dijon 2020 will provide a global vision of cutting-edge research, from the fundamental to applied, and including industrial developments and pedagogical innovations. An essential moment for fruitful exchanges in a friendly atmosphere.

OPTIQUE Dijon 2020 will emphasize the 60th anniversary of the laser, celebrated with a plenary lecture by Prof. Gérard MOUROU, 2018 Nobel Prize winner, as well as keynotes by Jean-Paul POCHOLLE (Thales) on a brief history of lasers, and Nathalie PIQUÉ (MPQ) on modern frequency comb applications, among others. 

In addition to scientific presentations, there will be a session devoted to relations with industry. Furthermore, an exhibit area for photonics industries, including start-ups, will be set up at the heart of the congress. An educational session will allow brainstorming on different teaching and dissemination experiments.

In cooperation with the SFO commission "women and physics, achieve parity in optics" the congress pays special attention to the number of women working in optics, at all levels of responsibility, and tends to ensure parity on OPTIQUE Dijon 2020 invited speakers. 

Some conference activities will be open free of charge to undergraduate and master students, with the help of Dijon campus.

LUCES SOBRE LA CIUDAD / LIGHTS ON THE CITY
 
Background
As a follow-up to the IYL 2015, and in response to the proclamation in 2017 of the IDL by UNESCO, a project is being developed in Mexico City under the title "Lights on the City", with the aim of proposing strategies to optimize the benefits of urban lighting and mitigate its negative effects on human health and the environment.
 
To carry out this project, a group of enthusiastic and committed members of a diversity of institutions, convened by the Mexican IDL Node and composed of specialists in ecology, human health, physics, astronomy, architecture, environmental engineering, atmospheric sciences, energy and lighting design, among others, have started work under the auspices of the Office for Education, Science, Technology and Innovation (SECTEI) of the Government of Mexico City.
 
Progress
The project group has identified the need to undertake a series of studies focused on the emission patterns of light sources, the interaction of light with the atmosphere, the day and night light environment in Mexico City, its spatial and temporal variations, its impact on the health and habits of citizens, on the urban landscape and public spaces, on the patterns of nightlife of plants and animals, as well as on astronomical observation.
 
The different ways of characterizing and quantifying lighting, its energy cost, the use of alternative energy sources and the design of luminaires will also be analyzed. International experiences that have been successfully adopted will be considered.
 
The results of this process will be a key input for the framing of recommendations, norms and policies aimed at providing the urban space and its inhabitants with optimal lighting conditions, in line with the sustainable development goals.
 
These works will culminate in 2022 with a proposal of clear and contextual comprehensive urban lighting strategies for Mexico City, in both public spaces and buildings, based on scientific research, technology development, innovation and professional practice.
 
Outlook for 2020
The group expects to resume its meetings once the COVID-19 pandemic is over. In the meantime, work on the project will be carried out at home and online as much as possible. Plans include the preparation of a report on the characteristics of natural lighting in Mexico City and the light requirements in different spaces, and a diagnostic monitoring of exposure to nighttime light pollution and its correlation with human health, as well as with biological processes of plants and animals.
 
Three collaborative workshops with stakeholder participation are planned to be carried out later in the year on specific topics, which would serve as laboratories of ideas and solutions for the development of city-level strategies. Contact will be made with Lighting Urban Community International (LUCI), to learn first-hand the experience of over 70 cities that already have programs for the use of lighting as a factor of social, economic and cultural growth.
