I don't know where you are but i heard it's around 4am UK time, and the Sky broadcast ends at 5am it says. This seems a bit early considering the fight is in California which is 8 hours behind the UK which would mean the fight is at 8pm there. I would imagine it'll be closer 5am UK time, unless they are starting very early over there.
Its sometimes better getting up for a big fry up and watching the re run where the main fight first or sky plus it! this has a undercard I like the look of so il be staying up,,,,,
I always do an all nighter to watch it live incase someone spoils the results for me somehow. That and the fact i have insomnia so i'm pretty much awake anyway.
If your in the UK don't stay up all night it will only knacker up your Sunday. Set the alarm for 5am you will be ok. Brook is the away fighter and not a draw so unlike the Hatton fights where its on a bit earlier this will go out at normal US western time.
It starts at 2am with 2 potential 12 rounders before it, It will be before 5am for sure, probably around 4am.
I just turn the phone off until I see the fights, used to stay up but with two kids under six its not fun trying to go to bed at 6 when they get up at 7!
I don't know how you guys do it. I would just record it and watch it when I wake up, avoiding the Internet so I don't know the results.
Don't get up at 5am. You will miss it...or most of it. 3:45am ideal get up time if you just want to catch the Brook fight.
Id say around 4am. I usually watch the next morning unless i come in from out on the town where i watch 4 boxers in the ring through one eye. Might stay up for this tho, i like all the lead up fights.
