Sunspot numbers, positions, and areas from observations by Johann Wurzelbau, 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 by Method I: sunspot positions are defined according to the time of observation reported by the observer.

Data format:


Draw - Number of drawing;
Place - Location of the observer;
YYYY - Year;
MM - Month;
DD - Day;
HH - UT Hour (Time of observation defined by means of Method I. Ephemeris, latitudes, and longitudes are calculated for this time);
MI- Minute (Time of observation defined by means of Method I. Ephemeris, latitudes, and longitudes are calculated for this time);
G - Arbitrary number of sunspot group;
Sp - Arbitrary number of sunspot;
BBB.BB - Heliographic latitude. Southern latitudes are negative;
LLL.LL - Heliographic longitude in the Carrington rotation frame;
B0 - Heliographic latitude of apparent disk center;
L0 - Heliographic longitude of apparent disk center;
P - Position angle;
Rot - Rotation angle of solar image in x-y plane;
q - Parallactic angle;
Alt - Altitude;
Azm - Azimuth;
Area_w - Area of the whole sunspot in millionths of the solar hemisphere (msh);
alpha - Angular distance on the surface of the Sun from the center of the disk to the area-weighted position of the object;
Time_obs_HH_UT - UT Hour of the original note of time of observation given by Wurzelbau;
Time_obs_MI_UT - UT Minute of the original note of time of observation given by Wurzelbau;
Time_obs - The original note of time of observation given by Wurzelbau.
