Title | | 'Preliminary study of the seasonal variation of optical seeing above Oukaïmeden site in the Moroccan High Atlas Mountains' |
Abstract | | The first seasonal variation study extended over fifteen months of
the night time seeing above the Oukaïmeden site is reviewed.
These data was measured in the visible during 137 nights distributed
along the period July 2003 - September 2004 with the Differential
Image Motion Monitor of Marrakesh (DIMMAR) on top of a 5 meters high
tower. From the whole campaign the mean seeing is 0.92", the median
value is 0.84" and the best seeing measured is 0.32". We determinate
that the best season is summer, its seeing median value is 0.78".
The best monthly median seeing, 0.60", is observed in september.
