Events

When to come

Sessions open to the public

The observatory’s sessions are published in the association’s calendar, which serves as the reference schedule for both sites. There are never two sets of dates to reconcile.

A session cancelled for weather drops off the calendar on its own. Past sessions that went ahead stay listed, which shows the observatory’s real activity.

No session scheduled at the moment. For any question, write to us.

Before you come

Every audience has its own way in

Inauguration on 11 December 2025; public sessions from 1 January 2027; bookings not open yet.

Once open, booking will depend on the activity: through the association’s HelloAsso activities, or through the calls on the portal. Until then, write to us.

Slots for amateurs and students require training on the equipment. Scientific projects go through the scientific committee.

What if I have a disability?

Mobility impairment. It is possible to follow our activities from the observatory’s control room, on the second floor of the building. Reaching the instruments, however, means taking a steep staircase: the spaces are only adapted as far as the terrace that leads to it.

Hearing impairment. Arrangements can be made on request. Write to us before your visit.

Visual impairment. Provision is being put in place. We prefer to say so rather than let anyone believe it already exists.
