Sunspot numbers, positions, and areas from observations by Maria Eimmart, stored in the Eimmart's archive, defined by Vokhmyanin and Zolotova (Sunspot Observations at the Eimmart Observatory: Revision and Supplement, in Solar Physics 2023).


Sunspot positions were gotten in two ways:
Method I: according to the time of observation reported by the observer (more specifically within the ±30-minute interval centered around the noted time of an observation);
Method II: the proper orientation of the solar axis and sunspot latitudes are defined by means of minimization of the day-to-day variability of sunspot latitudes. Ephemeris and longitudes are calculated for UT time of observation (Time_obs_HH_UT and Time_obs_MI_UT);
