Milky Way season in Sontra

The Milky Way's bright core never climbs 20° above the horizon during astronomical darkness from Sontra; the fainter band is still visible from a dark site.

• About 88.9% of the whole sky rises above the horizon at some point in the year from this latitude.
• The Milky Way's core in Sagittarius culminates about 9.9° up, staying low, so a clear southern horizon matters.
