What is a Ranger/SM40? A solar telescope? Who makes it?

By the way, I took the Ranger/SM40 out for a spin "on"
the Sun Tuesday morning, and was pleasantly surprised
to find a rather sizable (~1 Jovian diameter) prominence
on the following limb, in the northern hemisphere. A bit
difficult to describe in text, but it was thin the whole way,
shooting straight up and then curving in a gentle arc
down toward the equator.

Probably not there anymore, but maybe other activity
associated with the same area is.
