The rank of the strongest and weakest currencies has the EUR as the strongest while the AUD is the weakest.
Note however, that volatility for the major currency pairs are very narrow. The EURUSD has a range of 44 pips (the 22 day average is down to 95 pips). The USDJPY range is a narrow 31 pips with an average of 79 pips. Not much going on.
