The total solar eclipse on July 2, 2019, whose first totality at landfall
in Chile will occur at about 20:38 UTC, is being carried by NASA with a
feed from the Exploratorium science museum in San Francisco:

Unfortuntely, the commentator there, identified as a Ph.D., is describing
the event in legacy units. The commentator is one of those annoying
people who is trying to stir interest with feigned overenthusiasm for
children rather than let the scientific even speak primarily for itself.
What a missed opportunity to acquaint the students there with the actual
system (metric) that astronomers use. This is the kind of high-profile
opportunity that we have recently been discussing on this list. We need
to get NIST and the science organizations to get scientists to cover in
metric. --Martin Morrison
