This answer about Sun-grazing comets led me eventually to Wikipedia's Helion (meteoroid), which has a one-sentence long article:

A Helion meteoroid is a meteoroid that arrives from the approximate direction of the Sun. They are thought to originate as debris from sun-grazing comets.

It has one reference

"Exploding Lunar Eclipse", an article about an attempt to observe Helion meteoroids, Science@NASA, August 27, 2007.

but that link is now dead.

  • Was NASA's 2007 attempt to see meteoroids coming from a solar eclipse successful? What instruments were used?

  • Has it been attempted again since?

    $\begingroup$ Article available in wayback machine. It got a 301 redirect for the latest version, pretty sure it is still the same address except for the parameter. web.archive.org/web/20120910062131/http://science.nasa.gov/… $\endgroup$

    $\begingroup$ It's your reference, and I'm not up to a long answer, so I'll pass. $\endgroup$
