Narrative:
While being vectored for the localizer/FMS runway 25 at ege at FL250 denver center slowed us to 210 KTS (clean min/man was 209) because we were also turning and there was some light chop I called for flaps 1. As the flaps started to move I realized the 20;000 ft limit on the flaps applied and told the first officer to put them back up. While not excusing this I think the reason it happened was that this is a limit we seldom bump up against and the phase of flight and speed was where we normally extend the flaps. The fact that visually we were much closer to the terrain than 20;000 ft probably contributed as well. In the future I will add a reminder about this limit to my approach brief for high altitude airports.
