What satellite was it?

[Blue]

Whilst observing on the evening of 17th February about 2130 EST daylight saving, I noticed an odd satellite about 7 degrees South of Pollux. It showed an erratic pattern of flashes which lead me to think of a piece of junk that was tumbling which I have seen before but this one was hardly making much headway then disappeared after a period of some 15 minutes. I first thought of an Iridium Flare but only guessing. Was anybody else observing in that direction around that time??

Thanks
