Location: Alameda, CA
Shape: Light
Duration: 3 minutes
Characteristics: There were lights on the object, There were aircraft in the vicinity or aircraft chasing the object
Single object met up with two other objects and all 3 flew in formation. Unique strobe sequence.

Object seen traveling northbound up the San Francisco Bay displaying an unusual strobe sequence. Strobe sequence was a set of 3 followed by 5 seconds of no strobes followed by another set of 3 then strobing stopped and a faint light similar to a satellite glow became visible. No red and green wing lights visible. Object continued up the Bay then turned right heading over the East Bay. Object joined up with two other craft displaying the same 3 consecutive strobe pattern. All three objects faded over the East Bay until no longer visible. The strobe light sequence was different as seen on normal commercial aircraft which caught my attention and the flight pattern differed from the normal Oakland, San Francisco departure patterns. Could be military craft?
