What does the red-ring around an airport mean?

I was taking about this a lot. You can see what I mean in the picture:

Its knows as a TFR notifying you as a pilot of what’s required at that airport. To put the answer plainly as possible. Click on it to find out the goodies you have to abide by :)


To add on, if you click on it it will display a message telling you what the TFR means. In that case at OBBI one runway is closed and can be used as a taxiway.
