Antique Early 1900s Snapshot Photo Women & Photographer Holding Kodak Brownie Camera - Eclipse?

Original c1910 snapshot measuring about 2.5" x 2". Couple of light wrinkles.

The back is blank other than a single word in pencil, "Soleo" or "Solis"?"

I purchased this snapshot along with one other photo of a solar eclipse, so I believe these three were out taking a photo of the eclipse that day.
