Narrative:

Taxi instructions from ground control: taxi to runway 15, hold short of runway 06. I was performing the before takeoff checklist. Ground then instructed us to cross runway 6 without delay. The captain then made a hard left turn thinking he was crossing runway 06. There was no communication or forewarning on his part. We had crossed runway 15 in error. Ground reminded us of our error, clarified our clearance then issued progressive taxi instructions to runway 15. The current WX was no factor. I feel this was a crew coordination problem. I had no idea the captain was uncertain of where we were and where we were going. A simple clarification to ground control would have avoided this problem instead of just turning without forewarning. Also, we don't recall any runway markings for runway 15 - I feel this was also a contributing factor.

Title: UNAUTHORIZED UNCOORD RWY XING ENTRY.

Narrative: TAXI INSTRUCTIONS FROM GND CTL: TAXI TO RWY 15, HOLD SHORT OF RWY 06. I WAS PERFORMING THE BEFORE TKOF CHKLIST. GND THEN INSTRUCTED US TO CROSS RWY 6 WITHOUT DELAY. THE CAPT THEN MADE A HARD L TURN THINKING HE WAS XING RWY 06. THERE WAS NO COM OR FOREWARNING ON HIS PART. WE HAD CROSSED RWY 15 IN ERROR. GND REMINDED US OF OUR ERROR, CLARIFIED OUR CLRNC THEN ISSUED PROGRESSIVE TAXI INSTRUCTIONS TO RWY 15. THE CURRENT WX WAS NO FACTOR. I FEEL THIS WAS A CREW COORD PROBLEM. I HAD NO IDEA THE CAPT WAS UNCERTAIN OF WHERE WE WERE AND WHERE WE WERE GOING. A SIMPLE CLARIFICATION TO GND CTL WOULD HAVE AVOIDED THIS PROBLEM INSTEAD OF JUST TURNING WITHOUT FOREWARNING. ALSO, WE DON'T RECALL ANY RWY MARKINGS FOR RWY 15 - I FEEL THIS WAS ALSO A CONTRIBUTING FACTOR.
