'Coronet' is phenomenon, when a droplet impact at the surface of thin liquid layer. This phenomenon is related with surface tension, viscosity, impact speed, and droplet size. However, it has not yet been reported, whether gravitational acceleration affects coronet formation. The effect of gravitational acceleration was investigated using a parabolic flight experiments. At low Reynolds number, silicone oil does not coalesce with a thin film layer; bouncing was observed. At higher Reynolds number, droplet collides with a film and formed a coronet.
