(0:01) Hey folks, lets do a quick review of some Comet ISON Facts. We'll start at the JPL Orbital Diagram for C/2012 S1 ISON; it is currently inside of one AU (Earth's Distance from the Sun, at the white circle).
(0:16) Tilting to show the trajectory of the Comet from the Orbital Plane of Earth. You can see this Comet has a significant incline up-and-out of the system after it's fairly flat arrival.
(0:27) Now the first worry with Comet ISON was about meteors, because of how shallow the in-coming trajectory of the Comet comes in any break-up before it got to Earth's position could have left large chunks in our path, but, it just didn't happen and a dusting light show is probably the most we will see.
(0:45) But well before that, we will watch Comet ISON plunge towards the Sun. Here is the main concern at this time: despite the fervent denials of any connection between Comets and Solar Flaring by NASA and other experts, tens of thousands watching here every day and many more across the world watch Sun-diving Comet induce major flaring one after another; we'll discuss this more in a few minutes.
