Plena eklipso suna

That's how one says "total solar eclipse" in Esperanto.

I had the idea to make a sign that will say "Watch the solar eclipse" in Arabic. I found this page with multilingual, Romanized descriptions for "Sun," "Moon" and "solar eclipse." I also discovered that I've had the incorrect spelling of "Qamar"/Moon on my site for almost a year.

Ah well. Now I know.
