378 D. plexippus 4:08 30 m flap,
soar
straight,
circle
level,
climb
158° - 352° 4.9 m/s - yes - Butterfly was flapping along at 5 m when it encountered a thermal and began to soar in circles and gain altitude, climbing to 30 m.
379 D. plexippus 4:10 30 m flap,
soar
straight,
circle
level,
climb
163° - 347° 4.9 m/s - yes - Butterfly was flying level at 1 m when it encountered a thermal, probably the same thermal used by the previous two migrants, and began to soar in circles and gain altitude., climbing to 30 m.
Break - 4:11 - - - - - - - - - - - WW: Radar showed abundant targets up to an altitude of 1 km.  This was the maximum density of targets seen since the radar station arrived at the field site.
380 D. plexippus 4:15 15 m flap,
soar
straight climb 150° - 340° 4.5 m/s - yes - Butterfly climbed to a thermal and continued gain altitude while soaring straight ahead.  It never circled.
381 Underwing
moth
- 8 m flap straight level 158° right 344° 4.5 m/s - - - Moth (Noctuidae - unknown species) took off from the ground or from low vegetation.  Underwings usually hide on the bark of trees.
- - 4:23 - - - - - - - - - - - WW:  Targets were even more abundant than before (since releasing air sonde at 4:11)
