The Muon g-2 experiment at Fermilab*

The E989 collaboration at Fermilab aims to resolve the long-standing muon g-2 puzzle by performing a four times more precise measurement (140 ppb) than its predecessor of E821 collaboration at Brookhaven National Lab (540 ppb).  After completing the commissioning run in February 2018, the E989 collaboration has accumulated a dataset that is larger than the total statistics collected by the E821 collaboration. In this talk, the current status of the experiment, especially on the measurement of the muon spin precession frequency, the magnetic field and the muon distribution will be presented. Preliminary blinded results from these measurements will also be discussed together with the future plan of the experiment.
