what are we going to see today?

With such much volume the past few days, it'll be another interesting day.

Something I have not noticed before, but looking at eTrade it appears some strange orders have gone through around 7 this morning for some high prices. Is this a mistake - has anyone ever seen this before? Is it like a pre-auction?
Apologies for the questions. Here's what I can see:
