234th AAS Meeting Event Descriptions

Please note: The workshops and events listed on this page are only those that require or allow registration through the meeting registration form, and the ComSciCon-AAS 2019 event which has its own application/registration process. There may be other workshops and events during the meeting that are not listed here. See the online program (coming soon) for information on all events.

All workshop organizers, moderators, and attendees must be registered for the AAS meeting at which the workshop will take place. Those attending a workshop only and not the rest of the AAS meeting will be charged a one-day registration fee in addition to the individual workshop fee.


Planning for the 2023 and 2024 Solar Eclipses (1½-day workshop)

Saturday, 8 June | 9:30 am − 4:30 pm
Sunday, 9 June | 10:00 am − 3:00 pm
Organizer: Angela Speck, Univ. of Missouri, Columbia
Fee: $15
In August 2017 the continental US experienced its first total solar eclipse (TSE) in a generation. In April 2024, now only five years away, the US will have a second TSE, preceded by an annular solar eclipse (ASE) in October 2023. The AAS Solar Eclipse Task Force ran a series of workshops to prepare the nation for the 2017 TSE. These were instrumental in helping communities in the path of totality manage an influx of visitors; in developing and disseminating appropriate eye-safety information nationwide; and in coordinating the efforts of numerous scientific, educational, governmental, and other organizations to avoid unnecessary overlap. Now is not too early to start planning for the 2023 and 2024 eclipses, taking advantage of lessons learned from the 2017 event. This workshop is aimed at community leaders and other stakeholders both inside the paths of annularity (2023) and/or totality (2024) and outside, for — as in 2017 — the entire Lower 48 states will experience at least a deep partial eclipse. We are particularly keen to welcome participants from Canada and Mexico, as the April 2024 TSE also touches parts of those countries. Attendees are anticipated to include professional and amateur astronomers; formal and informal educators; representatives of tourism bureaus, Chambers of Commerce, and the hospitality industry; and officials from departments of transportation, state- and national-level parks and forests, law-enforcement agencies, and emergency-management organizations. Invited speakers will include event coordinators who experienced the TSE in 2017 and will see darkness again in 2024 (e.g., in SE Missouri and southern Illinois) as well as transportation experts and others who can present studies of the 2017 eclipse and offer recommendations for future events. We will also welcome a limited number of contributed presentations. For more information, see our Solar Eclipse Planning Workshop page.

ComSciCon-AAS (1½-day workshop)

ComSciCon-AAS 2019Sunday, 9 June | 9:00 am – 5:00 pm
Thursday, 13 June | 1:30 pm – 4:30 pm
Application Required
Organizer: Meredith Rawls, University of Washington
Fee: TBD

The ComSciCon (Communicating Science Conference) workshop series is partnering with AAS to bring a science communication training workshop to the 234th AAS meeting in St. Louis! We invite interested AAS graduate students to apply for ComSciCon-AAS, a free 1.5-day workshop intended to amplify the reach of the highly successful ComSciCon flagship workshop that has been held annually since 2013. Our goal is to empower future leaders in technical communication to share the results from research in their field to broad and diverse audiences. We especially encourage interested graduate students with little science communication or outreach experience to apply. Senior undergraduate students, post-baccalaureate researchers, and postdoctoral researchers are also welcome to apply, though preference will be given to graduate students.

ComSciCon is a unique professional development program focused on science communication skills, organized both by and for STEM graduate students. The program will consist of several panel sessions with invited professionals from AAS and the local St. Louis area, writing sessions where workshop participants hone their skills, structured in-person peer- and expert-review of writing, and a non-panel workshop to target a useful skill in science communication (topic could be data visualization, science storytelling, or improvisation, for example).

During the workshop, you will:

  • Learn techniques to improve written and oral science communication
  • Learn from professionals in topics relevant to science communication, including journalists or educators
  • Connect with diverse leaders in both astronomy and science communication and grow your professional networks
  • Produce an original piece of peer- and expert-reviewed science writing that can be published in one of ComSciCon’s partner outlets
  • Become part of the extensive ComSciCon alumni base and make new connections in astronomy and science communication
  • Receive one day of meals!

Inversion of IRIS Mg II h&k Data: A Machine Learning Approach

Monday, 10 June | 3:00 pm - 4:30 pm
Organizer: Alberto Sainz Dalda, Lockheed-Martin Solar and Space Laboratory / Bay Area Environmental Research Institute
Fee: $35
The Interface Region Imaging Spectrograph (IRIS) observes the chromosphere and the transition region to understand how the solar atmosphere is energized. Since its launch in 2014 it has recorded more than 18,000 data sets in the Mg II h&k spectral range. Recovering the physical information from these data is crucial to answer how energy is transferred from the lower layers of the solar atmosphere to the hot corona. We will demonstrate a new technique that applies to the Mg II h&k spectra that quickly (in a few minutes) enables the recovery of the thermodynamic information within the atmosphere. This new approach is based on several machine learning and artificial intelligence methods. In this workshop we will discuss the concepts, estimated errors, and limitations of the method and, in a hands-on environment, how to implement and execute the code we have developed.

Rodger Doxsey Travel Prize Fund

Contribute $25 or $50 to the Rodger Doxsey Travel Prize Fund
The Rodger Doxsey Travel Prize — established through the support of his father, John Doxsey, and other friends, family, and colleagues — provides graduate students or postdocs within one year of receiving or receipt of their PhD a monetary prize to enable the oral presentation of their dissertation research at a winter meeting of the AAS.

Purchase Carbon Offsets

Contribute up to $100 to the purchase of carbon offsets
Over 90% of the carbon emissions from a typical scientific meeting come from participant travel to the meeting. We are encouraging participants to contribute up to $100 towards the purchase of carbon offsets, which will be used for a variety of third-party certified projects to reduce carbon emissions. Offsets are not a panacea, but will go a small way towards compensating for the meeting's carbon footprint.
