Eclipse Megamovie 2024

Eclipse Megamovie 2024 (EM2024) is funded by NASA to discover the secret lives of solar jets and plumes. Many jets and plumes seem to disappear or change from the time they are formed on the Sun and when they move out into the solar wind. To learn more about these solar phenomena, we will use photographs taken by volunteers to identify solar jets as they leave the Sun's surface and solar plumes as they grow and develop. We aim for our research efforts to provide some clues or answers to this question.

What is a solar jet?

A solar jet, or solar spicule, is a transient, jet-like feature in the Sun's atmosphere. They are narrow streams of plasma that erupt from the solar surface, reaching high speeds and extending thousands of kilometers into the corona. Solar jets are relatively small and short-lived, lasting only a few minutes. They are thought to be caused by magnetic reconnection, a process where intersecting magnetic field lines rearrange and release energy. These jets are important for understanding solar phenomena, as they contribute to heating the solar corona and accelerating the solar wind. They are also significant in the study of space weather, which can impact satellite and communication systems on Earth. Solar jets are typically observed using space-based solar observatories.

Solar Jets and Plasma Plumes have been “hidden” behind necessary instrumentation discs on satellites used by NASA. The discs are used to protect “white-light” cameras onboard a satellite from the bright solar photosphere. These cameras are used to study the outer solar corona in the visible wavelengths. The inner corona is thus blocked, making it hard to study the evolution and motions of these plasma jets and plumes. Jets and plumes can be observed leaving the solar photosphere but then NASA has only had limited ability to track their motion off the Sun into the solar wind. Satellite cameras, like those on SOHO satellite, can pick up any jets that make it out to their field of view. But the jets that don’t make it that far cannot be studied. Ground-based solar telescopes can study these features by looking at their green emissions, which can get past the atmosphere. Other visible colors emitted from the scattered photospheric light off these features are blocked by the atmosphere, but are important for understanding the plasma jet and plumes’ densities and perhaps their evolution.

Using the citizen science python competition platform Kaggle Community Competitions with volunteer photographers interested in coding and/or data analysts who want to explore and characterize solar transient plasma flows and jets, we will lead an image processing competition using Eclipse Megamovie python codes created in the past 5 years together with emergent AI systems, processed EM2024 images in FITS files, and NASA SDO/ AIA and SOHO/LASCO data.

Thanks to improved calibration, equipment, training, and software processes, we will improve on the 2017 movie (solar min) and compare it to the 2024 movie (solar max). It is anticipated that returning volunteers will produce especially good data given the experience and learning they will build on from participating in Eclipse Megamovie 2017.

In the remaining year and a half of the grant, we propose to publish journal articles on solar discoveries such as velocities of transient plasma flows and jets. The proposed effort tackles fundamental issues related to flare energy transfer in the low solar atmosphere. The results of this investigation will provide important information about the generation, energetics and dynamics of solar flares, jets and flows and coronal mass ejections, providing crucial understanding of the initiation of space weather events.

The Eclipse Megamovie Project aims to add a new dimension to our existing studies of the Sun’s faint atmosphere, the inner corona. By stitching together thousands of images taken along the path of the 2017 total solar eclipse, we have already created a unique treasure-trove of information on how the corona changes over time. Radio-wave studies have allowed us to closely observe very rapid variations of the corona, but now we expect to study such processes directly using visible light and thus enrich our knowledge of the Sun’s dynamic atmosphere considerably. The data gathered via the Eclipse Megamovie Project will be made available publicly and are expected to allow scientists to analyze the Sun’s corona for many years to come. This will show how the Sun changes over a few hours, but also how it’s different after a period of seven years. The high-resolution processed images may also be shared with fellow solar eclipse researchers to incorporate into their own endeavors if desired, such as the work published by Pasachoff and Rušin in 2022 to understand the evolution of magnetic fields.

About our volunteers

Including the volunteers who will participate after the eclipse by helping to analyze the images of the eclipse taken by photographers in the field and the volunteers who are planning on photographing the eclipse and uploading their photographs (without any training or otherwise collaboration with us) we have over 500 volunteers. From these volunteers, we expect over 10,000 images of the Sun’s corona. Our volunteers have many different ways of participating, and here are the three primary ways they will participate:

1. Photographing the eclipse with an equatorial (tracking) mount while following our requested exposures. In other words, these volunteers are setting their cameras up for our images specifically, including very specific settings for things like aperture (or the size of the opening that allows light through to the camera sensor) and  ISO (how dark or light a photograph will be). The use of a tracking mount enables our volunteers to keep the sun fully centered in their photographs, ensuring a photograph that can be used to examine the sun’s corona for science. These volunteers will also take calibration frames in the form of flats, darks, and bias frames. These frames will allow us to know, without a shadow of a doubt, that what we see in the photograph is actually something seen from the sun, and not an “artifact,” or spec of dust on the lens or something else from the camera itself. This confidence in the image is critical for doing science with these kinds of photographs. We call these participants our STAR (Science Team Alpha Recruit) participants.
2. Photographing the eclipse without a tracking mount and according to much simpler standards. We have called this method the “2017 method,” because the settings that we have requested for the photographs match what we requested for the 2017 total solar eclipse. These settings are much less restrictive, and we anticipate the photographs to be beautiful and incredible. These photographs, however, may not be as helpful for the scientific study we will commence. We call these team members our
3. Image analysis via Python and Machine Learning and Kaggle Competition. This is a way to participate in the Eclipse Megamovie 2024 project without taking any photographs or needing to be in the path of totality. This is also the only form of participation that is available after the eclipse takes place. Our Python/ML volunteers will take the photographs that volunteers on April 8th took and use Machine Learning to align them. This is a trickier endeavor than it sounds, because the photographs will be taken from all over the path of totality. In order to properly align them, we need a lot of data from the photographer themselves, including calibration frames discussed above.

The EM2024 Discord server will be active and supported by EM2024 staff long after the eclipse itself takes place. This will also likely be a wonderful place to see our volunteers share the photographs they took on April 8th. This is also going to be the best way for volunteers to communicate with each other on April 8th as they make final decisions (based on the weather) about where they will set up to photograph the eclipse.

As of April 4th, 2024 we have 200 "STAR" volunteers, but we are calling them science participants. We have 358 MegaVolunteers, or MegaParticipants. And yes, we are looking for more participants. We also have 1,395 people on our general news listserv, many of whom signed up in 2017 but others who simply want to be kept abreast of any news about the project.
