The latest version of the Interferometric Precision Laser Inclinometer (IPLI) is presented. The results of microseismic activity measurements performed with the IPLI, as well as an evaluation of thermal deformations of the balcony serving as the base for the support of the beam extraction system to the MPD hall, are discussed. Based on two-week measurements, the diurnal angular oscillations of the balcony reach a value of 30 µrad.
