What is this symbol in my J3 Notification bar please?

Aha I cant submit a picture

Please forgive me I am autistic.

I get a plus symbol on my top display. It has a circle around it, with about 40% or so of the circle greyed out.

Does anyone know what the symbol refers to?


EDITED
Thank you It appears as though you are right.

Thank you very much!!
