4 1,500 Volunteers Needed Basic equipment necessary for participating in the Movie part of the Movie Project Camera: DSLR (digital single lens reflex) Telephoto or zoom lens: minimum focal length of 200mm A stable and level tripod Ability to identify the GPS coordinates and time to the nearest second

5 Movie Making Volunteer Details Receive training and submit a practice image Receive pin designating status as official photographer for project Your name included in credits of final Megamovie Visit eclipsemega.movie, log in with Google profile, select your location along path on Aug 21 and push save, indicate the 5 equipment you will have for photographing the eclipse and push save, select apply, and fill out application

6 Public Technology Involvement The public may participate in the Megamovie other devices than DSLRs We have developed with the help of private donors the Megamovie App We have been actively designing camera systems using low cost electronics based on the Raspberry Pi micro computer All the software and hardware will available to the public soon, so that they can modify and get involve in prototypes for the next total solar eclipse

7 Methods of Photography for Volunteers DSLR Cameras and telescopes. Software such as Solar Maestro can be used to operate the camera. Raspbery PI - Picamera Set- Up Mobile phones + telephoto Megamovie App

8 PiCamera Hardware: RaspberryPi boxes setup Primary Electronics: Primary Raspberry Electronics: Pi Raspberry Pi GPS HAT + GPS antenna HAT + antenna PiCamera PiCamera Module Sensor Module Sensor HAT HAT

14 Megamovie Scientific Objectives The Total Solar of in Wuhan, China 1. Baily s Beads, lunar topography, solar limb darkening, and the solar diameter As proved by observations of the annular eclipse in Argentina, all the devices available for the Megamovie can clearly register Baily s Beads and therefore the diamond ring effect (Baily 1836). We plan to measurement the solar diameter (e.g. Sigismondi et al. 2009) using these data. Such observations will precisely measure the solar diameter (e.g. IOTA, 2007) and the limb-darkening function (Weart and Faller, 1968; Raponi and Sigismondi 2011), a distinct property of the solar limb (e.g. Petro et al. 1985; Kuhn et al. 2004; Fivian et al. 2008; Emilio et al. 2015).

15 2. The behavior of the corona on varying scales This general topic embraces several distinct phenomena, all potentially interesting for the Megamovie perspective. By their nature, the heating activity induces flows as the corona and the lower atmosphere strive to re-establish hydrostatic equilibrium (e.g., Tomczyk et al., 2007). These flows constitute one of the primary objectives of the Megamovie scientific work. Another objective of the Megamovie project is the detection, study and characterization of episodic events such as flares and CMEs. If possible study the possible excitation of resonance behavior (oscillations) generated by transient phenomena as flares and CMEs, therefore contributing to the field of coronal seismology( Roberts et al., 1984) Source: Pasachoff, et al. 2015

17 Education and Outreach The Megamovie Project team has been making educational tours in cities, and towns along the path of totality, educating people about the total solar eclipse. The project already have more than 1000 trained scientifically literate and skilled photographer volunteers, ensuring the quality of the primary dataset. The Megamovie app is ready to be used by the public. New tools are been developed to engage the public in the analysis of data

18 Education and Outreach The Megamovie project has server as a platform for REU students to be engage in instrumentation design and testing. Other part of the solar scientific community (Sunpy community) are ready to contribute to the analysis of the data gathered by the Megamovie project. The Latin-American astronomical community had expressed their desire to mimic the Megamovie effort for the upcoming 2020 Total Solar.
