What is the notification icon?

[AC Question]

I have had a Note 3 for over 2 years and this morning I saw a new notification bar icon for the first time. I opened the notification section and none of the lines matched the icon. I started closing each line one by one and the icon remains. I hit the clear button and the icon remains. I went to the battery usage section and I did not see anything like the icon. I have not installed any new programs in the last week. The icon is 2 circles, the second circle is about 1/3 the size of the first. The second circle is centered on the edge of the larger circle at about the 2 o'clock position. Dose anyone know what this icon represents?

Welcome.
That sounds like it could be the Google + Circles icon.
Someone may have added you to their circles and it gives you this notification.
Let us know if that is is.
Thanks.
