Pomoč pri iskanju geografske lege vaše astronomske opazovalnice.
A) Pojdi na Naravoslovni atlas (potrebna je e-mail prijava) http://kremen.arso.gov.si/NVatlas . Določi ravninski x in y koordinati Gauss-Krugerjeve projekcije.
B) Pojdi na online program za pretvorbo iz g.k. koordinat v sferične - geografske. Program je bil narejen za potrebe Astronomskega društva Vega Ljubljana.
Oglej si tudi tekst o Gauss-Krugerjevi projekciji.

Spodaj so podatki za Observatorij Gimnazije Šentvid Ljubljana, dobljeni z omenjenimi orodji.

Results

In this table you get for each of timed contacts:
  • the value of the average distance of the Earth from the Sun (astronomical unit, AU) calculated from your measures,
  • the corresponding value of the angle under which would be seen the Earth radius from the center of the Sun (Solar parallax Π),
  • their shifts from the exact values Δ(AU) et Δ(Π),
  • the percentage of error of these values.
At the bottom of the table, you get the average value of the whole set of measurements.

Position of your results with regard to all the measures

The graph below shows the distribution of the measures of the astronomical unit performed at this moment:
  • The number of observers for every slice of values of the astronomical unit is represented by a vertical bar.
  • Tour own measure is represented by a green line.
  • The exact value by a red line.
