DMS-members Klaas Jobse, Jaap van 't Leven and Peter Bus observing the Leonids 2000
Due to the excellent results we obtained during last years' Leonids storm, we (Peter Bus, Klaas Jobse and Jaap van 't Leven) decided to head for Portugal again. Peter and Jaap arrived at Faro airport in the evening of november 12. With the arrival of Klaas the following wednesday the team was complete.
