Thanks, Tom. I have read several papers on various technical/scientific on
eclipses but there are always so many more...

Some friends of mine from the University of Nottingham are coming over to
gather some data for dark matter studies. My spouse and a colleague from
Singapore are hoping to get their hands on some data for re-analysis that
will be collected by folks from MIT.

All in all, an exciting time.
