TEMPORARILY CLOSED

Effective at 10pm MST on January 7, Lowell Observatory is temporarily closing our on-site visitor programs due to the increasing surge of COVID-19 cases in our community. Our doors will remain closed until the surge of local cases has significantly diminished. 

It is with heavy hearts that we return to a full public closure, but we eagerly look forward to re-opening our doors to all of you once the level of community spread permits it.

Follow us on social media for updates to our status, and to engage in our exciting digital experiences.
