Jeffrey has a great post up about the rate at which Iran’s centrifuges are operating.

Among the most interesting items is this bit o’ math:

Between April 15-May 22 (37 days, not counting the 22nd, or 888 hours), Iran fed approximately 260 kg of UF6 into the eight cascades. Assuming a feed rate of 70 grams an hour, eight cascades should consume approximately 500 kilograms of UF6. If Iran consumes just 260 kilograms, than the centrifuges are operating a little above 50 percent of what one would expect.

Read the whole thing, though.

In a somewhat different vein, I give you a visual representation of Iran’s response to the UNSC demands. Happy Friday.
