LOFAR Family Meeting to konferencja naukowa, podczas której spotykają się radioastronomowie z całego świata, wykorzystujący w swych badaniach wyniki obserwacji wykonanych radioteleskopem LOFAR. Ten unikalny przyrząd, składający się z osobnych elementów rozlokowanych w kilku krajach Europy, działa na zasadzie interferometru radiowego, chociaż każdy z elementów jest w istocie niezwykle skomplikowanym systemem anten.

Spośród przeszło 50 tzw. stacji systemu LOFAR, trzy ulokowano na terenie Polski. Stacja będąca własnością Uniwersytetu Warmińsko-Mazurskiego w Olsztynie znajduje się w Bałdach.

W programie konferencji, zaplanowanej w dniach 12-16 czerwca odbędzie się wiele sesji tematycznych, podczas których uczestnicy, a zjawi się ich ponad 150, przedstawią wyniki swoich badań, a także wykłady przeglądowe.

Wśród zaproszonych gości znaleźli sięPhilip Best, Rossella Cassano, Marcin Hajduk, Volker Heesen, Jason Hessels, Leon Koopmans, Leah Morabito,  Anna Nelles, Shane O'Sullivan, Hanna Rothkaehl, Huub Rottgering, Dominik Schwarz, Cyril Tasse i Pietro Zucca.

LOFAR jest instrumentem pozwalającym na badanie bardzo szerokiego wachlarza zagadnień, zatem tematyka obejmie pogodę kosmiczną i badanie Słońca, pomiary ośrodka międzygwiazdowego, wyniki obserwacji gwiazd, w tym bardzo egzotycznych pulsarów, ale przede wszystkim wyniki obserwacji najdalszych obiektów w znanym Wszechświecie, radiogalaktyk i kwazarów, co jest niezwykle ważne w zrozumieniu tematów kosmologicznych.

Część wyników prac badawczych zostanie przedstawiona w postaci posterów, których kilkadziesiąt na czas trwania konferencji ozdobi dolny hol Centrum Konferencyjnego UWM w Olsztynie, gdzie wydarzenie będzie się odbywało.

Lofar Family Meeting wpisuje się w obchody Roku Mikołaja Kopernika, dlatego zaplanowano specjalne spotkanie w Zamku Kapituły Warmińskiej, podczas którego przedstawiona zostanie sylwetka wielkiego polskiego astronoma.
