Earlier in the night, I was at Dave's meteor watch session at Bishan Park for a short while. Met Dave, Bornfree & Hong Lian (hope I remember your name correct) and hope you guys have a fun night. Did a 150 interval shots sequence there when the north sky clears a bit but photos only show endless clouds cover with small patches of clear sky areas. Nothing of interest

Went home at 11:30pm to rest and resume interval shoot from my house balcony at around 3 plus. In the last set of 100 interval shots (26mm, 15 secs each, iso500, f/3.2) which starting at 4:35am, it seems that "something" was captured in one of the frames. This is the photo:

Only did some simple adjustments in PS - exposure, contrast, clarity, noise reduction and adjust levels to tighten the black & white range.
Need some help/comments/guide here on how to determine whether this is a meteor or satellite?
Additional info:
Time stamp - 11 August 2013, 4:43:18am
Camera was pointed towards 20-25 degree north-east direction, about 50-60 degree tilt.
Based on skysafari app, the center of the "something" was at 352 degree north and 60 degree above horizon.
btw a slight glimpse of andromeda galaxy can be seen at the left side of the tail of the "something"

If there is more info needed, pls let me know. big thanks!
