Trouble with hatch *Ch 2 Spoliers*

[kiera.smz]

I finished getting the spear and was on my way back to Jeremiah, and decided I would get the Aurora's Hatch while I was there. Well, I've camped outside of it for 20 nights, waking up every hour, and there hasn't been an Aurora. I can understand it's rare, but after 20 consecutive nights, I'm starting to wonder if I'm doing something wrong. 

Do I have to progress the main story further before another Aurora happens? Or am I just getting unlucky?

I once waited almost 30 days in game for the aurora to appear in episode 1 so I could use the elevator in the dam.  I think it's just a waiting game sometimes...
