Yesterday evening was certainly a tough one. Mrs. Marta Mąkosa, Jan Struziński and Michał Rembalski emmited light signals from the pier in Sopot with the light emitter. Adam Dąbrowski, Anna Rzepa, Mateusz Mazurkiewicz, Kamil Iwanowski and Adam Cichy were locating the light from the pier in Gdansk Brzezno with a telescope. Mrs. Agnieszka from the Gdansk University of Technology was helping us. We managed to locate the Sopot team and take pictures of the spectrum. We are very thankful to Mr. Adam and Mrs. Agnieszka for their help.
