Freier Bericht

A very interesting day. Ridge, thermals and wave! In the beginning of the flight, some wave clouds were present, but they didn't do the trick. Sometimes, the wind seemed to be a bit less than forecasted (both in direction and intensity), but with the strong sun heating the slopes, it was possible to fly thermodynamic. Towards east the ridge was working less, while the west part had stronger wind, was reliable and quite easy to fly. While in height the wind seemed to rotate Westwards, in the lower level it was South, and I think even South-East/East. Far towards west, the ridge was reliable, especially at noon time when the thermal peak was at its maximum. The cherry on the top, a first thermal of the season at Süntel which made it possible to transition into wave. Then an unsuccessful try to find a primary wave at Hamelin, and a short extension towards Bisperode/Hellenhagen where I found another small wave. I did not dare to get lower on the ITH ridge with the given wind direction (see flickr photos). I jumped up and down in this waves a few times, but after I reached the peak at 2047 MSL, the next attempts were weaker. On the last leg, flying towards home, I stopped briefly at Schaumburg to try the wave there, but it was very weak.
