Day 12 (?)

Now we're witch hunting. Our turn of duty never came into place — the shift before us noticed some movement on the screen, which couldn't be explained by the dust. For the last twenty hours, I think, all of us were sitting in front of the monitor, rushing for a coffee or a tea every once in a while. I haven't been able to close my eyes yet and got very tired, so I decided to go into my room, make notes and sleep for a couple of hours.
We've re-checked the tape for a thousand times, I guess. It was a nighttime on the planet, which makes it more difficult for us. Adding lights onto the tape didn't really help — the colors on moving object are similar to those of the local ground. We stop can't be certain, whether it's some geological effect or a living creature. Of course, we've already established a circle with two kilometres long radius, which we're scanning through. So far we went through the central part, but we didn't find anything, except for those weird bubbles, that are now almost trying to get on to of each other.
I'm going to bed now; John promised to wake me up in two and a half hours, if I won't get up on my own. I hope if something happens before that, he won't feel sorry for me, so that I won't miss anything.
