This database is a live homogeneous database of solar active regions based on SOHO/MDI and SDO/HMI synoptic magnetograms. It provides several basic parameters, including the latitude and longitude of the flux-weighted centroid of two polarities and the whole AR, area, and flux of each polarity. The CR number and label jointly serve to identify a unique AR. More parameters, including polarity separation, tilt angle, initial dipole moment, final dipole moment, and ARDoR, will be given in the future work of the series. There are 2849 ARs in the database, with 1481 ARs in cycle 23 and 1098 ARs in cycle 24. The database covers a large range of ARs, from 136 μHem to 30122 μHem. The database currently covers the time range from May 5, 1996, to June 14th, 2023 (CRs 1909 - 2271) and includes cycles 23, 24, and part of 25, with continuous extensions planned. It can be used for not only the long-time variation research of active regions (space climate) but also solar cycle prediction.
