True to tradition, the Association of Former Leiden Observatory Students and Staff (VO-S) has an informal gathering prior to the annual Oort lecture.
Meet and catch up
The VO-S focuses on establishing and maintaining contact between former and current students and staff of the Leiden Observatory. Therefore, the VO-S organises the opportunity for its members and all other interested parties who are or were connected to the Observatory to meet and chat with each other over drinks. The gathering will take place in café Barrera directly across the Rapenburg from the Academy Building, where the Oort Lecture takes place.
Join us!
Non-VO-S members are also welcome to join this drinks party, provided they have studied Astronomy in Leiden or have worked or work at the Leiden Observatory. The costs for non-members are 5 euros, but there is also the possibility to become a member of the VO-S, which makes the drinks free of charge.
