23may12:strobe lights from yiye avila's tower on mount roncador

Update jun12: Angel talked to the tower manager. He said the red lights that were there failed. They will get new red lights then discontinue the use of the strobe.

    Strobe lights have been seen coming from atop the mountain range behind the observatory for at least the past few months. On 21may12 I made a video of yiye avila's tower starting around 18:30. The setup was:

• canon sx230hs camera
• 56x zoom (14 optical, x4 digital).
• shaky tripod standing on the grass below my house (about 1km north of the observatory).

•  There are two strobes, one 1/2 way up tower (just below the donut). The second strobe is at the top.
• Later that evening a made a second video using the high speed (slow motion recording in the camera..yes  all this for $200..).
• At 240Frames/sec  the strobe was seen in two frames (multiple times).
  
• 1./240 =4.1 millisecond. So two frames is about 8 milliseconds
• The strength of the strobe lights was not the same in the two frames, so part of the duration may be that the two strobes are not exactly synchronized
