Bright star size pulsing object moves accross sky in westerly direction

Looking up at the sky in a southerly direction at 7:20 PM on Monday March  21st I noticed a pulsing light as I looked up at the sky at approximatly a 70 degree angle.the pulsing light appeared to be moving in a northerly direction coming toward me as I looked to the south. I thought it was a High flying plane. The light pulse of the object was unusual in that it pulsed about every 5 to 10 seconds and was very bright...about the brightness of a medium to bright star. It cought my attention because of its unusual pulsing timing.The object pulsed about 4 times and then after the 4th pulse I could see the object as a speck or dim star size light streak accross the night sky in a westerly direction in a slightly arching pattern and disappeared.
