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 się: Philip 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.
