There are two geomagnetic observatories running in the framework of Bogazici University, Kandilli Observatory and Earthquake Research Institute (KOERI) in Turkey. Those are Istanbul-Kandilli (ISK) and Iznik geomagnetic observatory (IZN).The former is the oldest one and started its systematic observations in 1947 and still working since then. It became a member of INTERMAGNET on its 50thanniversary in 1997. In 1947 the population of Istanbul was about one million and the Kandilli Observatory was in the country. However, nowadays the population is about 15 million and rising, so the city has begun to threaten the observatory records. Therefore, to continue the geomagnetic observations in Turkey, KOERI set up a new geomagnetic observatory, IZN, near Iznik about 100 km to the southeast of Istanbul in 2005. IZN has become a member of INTERMAGNET since 2007. In this paper, we report on our experiences, challenges and results of analysis of our geomagnetic data. These data provide valuable geomagnetic field information on Turkey, east of Europe, west of Asia. Finally, Next goal of KOERI is the
creation and upgrade of new magnetic observatory at the east of Turkey with INTERMAGNET certification.
