SIU leads nationwide NASA project
to gather data from sun during 2024 eclipse

Researchers
at Southern Illinois University Carbondale will equip, coordinate
and train teams of student eclipse observers across North America,
playing a vital role in NASA’s plans to study the rare celestial
event in April.
The team of SIU researchers, led by co-principal investigators Bob
Baer and Matt Penn, will use a two-year, $314,000 NASA grant for the
Dynamic Eclipse Broadcast Initiative (DEB) effort. The citizen
science project will have more than 40 teams largely made up of high
school and middle school students – in sites spanning from Mexico up
through the United States and into Canada – use telescopes to
provide critical coronal data as the moon’s shadow traverses the
continent.
The effort not only will result in valuable data but also real-time
views streamed online and broadcasted in cooperation with NASA EDGE.
“We’ll be fulfilling NASA’s citizen science strategy by engaging a
diverse, emerging group of citizen scientists as volunteer
observation teams,” Baer said. “By including volunteers outside the
path of totality, we include the majority of Americans in our
potential volunteer base.”
Baer, a specialist, and Penn, an adjunct assistant professor of
practice, both in in the School of Physics and Applied Physics, are
leading the effort along with other SIU faculty and other
universities.
Baer and Harvey Henson, director of the STEM Education Research
Center, are leading an additional grant contributing to DEB and
funded by the National Science Foundation. SIU’s subaward on the
grant led by Cosmic Pictures, the filmmakers of “Einstein’s
Incredible Universe,” an IMAX movie that focused on the 2017 total
eclipse, will push the value of SIU’s DEB effort up to more than
$530,000, not including additional private donations.
Altogether, enough funding exists for 70 DEB teams, Baer said.
“Citizen science projects like this one get the public involved and
excited about doing science in a big way,” Baer said. “This one is
especially cool, because the volunteers will be collecting real data
for NASA.”
A big job
So far, about 25 teams are in place, with many more to go, Baer
said. Each team includes about five members and a team leader. The
teams are strategically located in or near the path of the April 8
total eclipse and are often associated with a nearby university or
community college.
A diversity aspect of SIU’s effort will specifically aim to create,
equip and train 20 teams made up of middle school-age girls, in an
effort to spark their interest in science.
The grant money is paying for dozens of 40mm telescopes to equip
each team, and about 10 teams already have received their telescopes
and are training with them. Baer is now working with manufacturers
to provide the balance of the scopes needed.
On eclipse day, the teams will use the telescopes – each less than
one foot long – to observe and record coronal activity that is only
visible during totality. The grant money also is purchasing
astrophotography cameras to fit each scope and capture important
images.

Baer and Henson also are helping create printed materials and
videos, aimed at training each team leader – usually a college
student or other adult. This fall, the leaders will begin
training the team members to operate the equipment and collect
images and data.
The first teams will have a chance to test their skills during
an annular eclipse in October. Even though such an event does
not provide the opportunities to collect coronal data as a total
eclipse event, Baer said, the teams can still make direct disc
observations of the sun and collect important data, while
becoming more familiar with their equipment.
“We’ll get a lot of science out of that,” he said. “We’re
getting people involved and interested.”
DEB builds on 2017 project
SIU lies directly in the path of totality for the April 8 eclipse,
just as it previously did in 2017, making the university and the
area the eclipse crossroads.
During the 2017 eclipse, SIU also was involved in the
Continental-American Telescopic Eclipse Experiment, another
nationwide telescope network of citizen scientists. The effort was
led by Penn, who at the time was an astronomer with the National
Solar Observatory.
The Citizen CATE Experiment included about 70 observation teams
nationwide, roughly one every 40 miles along the path of the 2017
eclipse. Baer, who also is co-chairing SIU’s eclipse committee this
time around, acted as a coordinator for several Southern Illinois
CATE teams, including teams at Pope County High School, Giant City
State Park, the Bald Knob Cross of Peace, SIU and the airport in
Perryville, Missouri.
“CATE was the most popular citizen science project in 2017,” said
Baer, adding that his co-PI, Penn, reported before Congress on the
effort’s success. “DEB is a follow-on project to Penn’s CATE. We’re
taking what was good and improving upon it.”
SIU research team makes it work
Along with Baer and Penn – a physicist who studies the sun and the
main science officer in the effort – several other SIU faculty
members also are heavily involved in the project. Cori Brevik,
assistant professor of practice in the School of Physics and Applied
Physics, is focusing on recruiting and organizing the dozens of
teams, while Henson is focused on developing training and research
materials. Karla Berry, associate professor in the School of Media
Arts, is assisting with digital content creation.
“This is very much a team effort, here at SIU,” Baer said. “We have
very dedicated researchers and scholars who are giving their all to
get ready for this event.”
SIU also is partnering with faculty at the University of Michigan,
University of Illinois, Moorhead State University, California State
University-Northridge, Vincennes University, Westminster College and
Langara College in Canada.
