Route Notes	"Wonderful weather" on summit day. Both members left C3 27 Sept 3:30 am NST. Perko to 7600m, too cold and returned C3, while Dobrajc on to top at 9:45 am, saw Everest and Lhotse. Perko slept 27th at ABC, but Dobrajc in C2, which he reached with Paulo Coelho. Dobrajc used oxygen in C3 on night of 26-27th to top and to C3 only. Perko used no oxygen and probably for this season was too cold. On 27th 300 people queued to use fixed ropes.
