Narrative:

Departing jyo. Part time tower closes in the afternoon. Called ground for clearance. Was informed tower was closing; runway 35 was in use and to get clearance from potomac approach. Announced taxi to runway 35 on unicom and taxied to run-up area. Switched frequencies and got IFR clearance. Was told there was inbound IFR traffic and that we were cleared to go as soon as they arrived. Traffic was on base for 35. They landed and we announced our departure for 35 on unicom and taxied out. As landing traffic cleared runway we started our takeoff roll. As we rolled I spotted landing lights on short final for runway 17. I aborted takeoff and stopped the plane well to the side of the runway. The approaching airplane; a cirrus; landed and taxied off the runway. We then departed on runway 35. I do not believe the cirrus ever saw us. We did not hear him call position or intentions on unicom. The wind favored runway 35 and that was the direction all traffic had been landing according to the tower before it closed. The runway is long and neither airplane was in jeopardy as the cirrus stopped in a short distance and exited the runway. But had I not seen them in the distance it could have been much closer.
