A pdf version of the summary of the General Assembly schedule can be found here.
Only plenary sessions (meetings of the whole General Assembly) will be streamed. That means the only streaming on Sunday, June 15 will be from 2:30-4:30 pm, and there will be no live streaming at all on Monday or Tuesday, June 16-17, because that's when the General Assembly committees will be meeting.
Most observers have found that the most interesting time to watch live streaming is on Saturday evening (June 14), when the new moderator will be elected, and, later, on Wednesday evening (June 18) and all day Thursday and Friday (June 19-20).
It's not clear at this time when the various committees will be reporting. although this information will be available later in the week on PC-Biz. (Search for "docket" under the Explorer tab, or search for the Bills & Overtures Committee report (which recommends docket amendments).
In past years, the most controversial items have been scheduled for Friday afternoon and evening. If there are more than 2 or 3 controversial items, one of them may be scheduled for Thursday as well.
