* Latitude: 17°
* Sun travels west around the sky! Angle was 18° from being at right angle to the horizon (72° west).
* Axis pitch: 35°!!!

===Rotation center of the sky===
Finding the rotation center was quite simple.<br>
First, a look directly up in the sky, facing magnetic north. This picture was taken by clipping many pictures into one:<br>

By looking at the picture we surprisingly concluded that the visible rotation center was somewhere near the western horizon, and not north or south as on earth.<br>
'''Conclusions:'''<br>
* Wurm's geographic north (as we define it on earthrotation center) is towards Wurm's magnetic west. * The sun Sun rises in magnetic north (geo. east) , travels around magnetic east (geo. south) and sets in magnetic south (geo. west). * Sky rotates counter-clockwise around the visible rotation center.
* We're located on the geographicaly north hemisphere of the Wurm planet (magneticaly west).

===Latitude and current axis pitch===

Finding the axis pitch was quite easy after we found the latitude. We just looked straight up and took a picture when the time was 12:00, calculated the angle to the sun.<br>

===Final comment===
Wurm is a very strange and interresting interesting planet. Even though it's in the middle of a pole switch and the current axis pitch is around 35° (which would be absolutely fatal for the life on planet earth), it is full of life and is very habitable.
