The Robert Ferguson Observatory is deferring to state and Sonoma County guidelines, which still require anyone who isn’t vaccinated from COVID-19 to wear a mask in indoor public settings. If you are not feeling well or have a fever, please stay home. Please note that all guests are required to show proof of full vaccination or a negative COVID test within 48 hours in order to attend a live event. Thank you!
