Google+ Listings - Strange

[CsmBill]

I was doing keyword research, and for some of my keywords I was seeing Google+ listings last week. they were gone earlier this week, but now they are back. We weren't in them anyway (new project) but can anyone explain this? Same computer, Same IP,

Here is an article by Mark Traphagen: Google+ Profile PageRank: The Real AuthorRank? - SMX Advanced 2013 in which he mentions G+ pages in the SERPs. The Google+ Fitness and Nutrition community was apparently ranking on the first page for "fitness and nutrition", though this week they are on page two. Perhaps we will be seeing more of this.
