The radiotelescope will be temporarily closed to the public January 16 to 20, 2014.
They are inspecting to see if the facility sustained any damage in the M6.4 earthquake we had on 13 January 2014. If no damage is found, they will reopen on 21 January. If you plan on going there 21 January, call or check their website first to make sure they are open.
Not sure what will happen if they find damage.
