AbstractThe paper presents the component measurement results of plumb-line deviations (PLDs) with a digital astrometer at the Moscow gravitational anomaly (attraction). The anomaly was first discovered in the 1850s by B. Ya. Schweitzer, Professor of Astronomy of the Moscow University. The paper is based on the conference talk made at “Astronomy yesterday, today, tomorrow” (Sternberg Astronomical Institute, Lomonosov Moscow State University, 14–16.10.2019).
