Heweliusz - the second Polish BRITE satellite was successfully launched from the Taiyuan Launch Space Center (China) on Aug 19, in early morning hours (Polish time). A few hours later the communication team from Nicolaus Copernicus Astronomical Center received the first signal from the satellite and established a communication link. Since then the communication with Heweliusz has been established during every flight session.
