[Hugh Hudson]

Thanks, I'll incorporate all of that. I think my memory was faulty about Shadia's 2011 paper and multiple sites, but I think your wording is fine. For your ApJ 742 paper I was just looking at the abstract, which says "No large-scale dynamical phenomena were seen."  It is a worry that even with extended coverage in 2017 we may not be so lucky.

I also put paragraph 2 into past tense, since the 2012 eclipse would be in the past when the abstract is printed/read.

I don't see that Shadia's 2011 paper had multisites, and an ADS search for Shadia in 2011 shows her multi-wavelength work but not multisite work.  So perhaps someone should/could verify just how to describe her reference.

>> A total eclipse [on 21 August] 2017 will traverse the full breadth of the United States[, from Oregon to South Carolina,] and last for an hour and a half[, with partial phases visible from the entire continental U.S.]. We [are starting ]to organize a large effort to acquire and reprocess many still images of the corona into a "Megamovie," or rather a series of [Megamovies] depending upon the quality of the input data. This effort aims mainly at public outreach, and we intend to sponsor activities to enlist schools in the eclipse path among other amateur participants. The movies may also have scientific content, since many kinds of coronal variability do occur within this time scale. Whereas true variability is sometimes difficult to detect on these time scales ([though some successes have occurred], e.g., the recent multi[typo fixed: "multi" had two "i"'s]-site results from Habbal et al., 2011, [Astrophys. J., 734, 120-137]  and Pasachoff et al., 2011[, Astrophys. J., 734, 114-123; Pasachoff et al., 2011, Astrophys. J. 742, 29-42]), a lucky sighting of a CME or other transient could occur at any time (e.g., the 1860 eclipse described by Eddy, 1974 [Astron. Astrophys. 34, 235-240], as possibly the first CME sighting). Since the eclipse corona extends to the very surface of the Sun, [and changes with the sunspot cycle,] such a sighting would have clear scientific value and should be documented well if at all possible.

>> For the Coral Sea eclipse [observed from the coast of Queensland, Australia, on 13/14 November 2012,] our team [attempted] to carry out a first rehearsal of our plans for 2017. This effort [included our first cut on ]multiple outreach activities, instruction on eclipse observation for inexperienced observers, the establishment of Internet-based tools for data transfer, the acquisition of as many eclipse images as possible (with their metadata), and finally the processing of these images into movie format. Among the Web-based tools we are working to provide an app for smartphones, with the idea that at almost any amateur snapshot can contribute at least to a record of Baily's Beads. This app will instruct and guide observers, and help to record the metadata for their images.
