Flight #12

Today we decided again to fly to the east coast. After takeoff we performed a low level leg along the coast line on our way to Ragged Point at 300 ft (ACTOS) above sea level. Afterwards, we ascended to get a vertical profile near the east coast. Reaching 8000 ft we recognized a very stratiform cloud which was located just a few hundred feet higher. So the pilots asked for permission to climb up which was immediately approved by ATC and we performed measurements inside a homogeneous cloud at 8500 ft for more than 10 minutes (see upper picture). A very nice optical phenomenon came along with us - within the shadow of the helicopter a glory appeared (lower picture). Thereafter, we descended to sample cumulus clouds at various altitudes from 4000 ft to 6000 ft for another 45 minutes. Cloud base was mostly located near 2000 ft and cloud top very variable. Finally, we flew again horizontal legs under cloud free conditions at 3000 ft and a low level leg near Ragged Point on our way back to Concorde Helipad.
