On Saturday, we flew with the SOA package into the night to observe the particle growth and change of particle properties during formation of atmospheric layers. The flight started at 10 p.m. before sunset and ended at 2 a.m. in the morning when it was almost dark. Heavy instruments were removed afterwards. On Sunday, we prepared the Nucleation flight for Monday morning.
