[LED Video]

  It was succeeded in the video of the FITSAT-1 LED (10Hz) on 14 Dec 2012
  by Toyama Astronomical Observatory in Japan. Because they pursued FITSAT-1,
  it seems to us so that the many stars flow through the back of a satellite
  flashing on and off small in the vicinity of the screen center.
  Note: In the video, they are many ordinary stars not the meteors.

[LED Schedule Update]

  23:01-23:11JST, 17 Dec 2012, Ele 62 NW-W-S-SE
  The flashing planned time over Japan, it's 2 minutes of 23:05:30-23:07:30JST.
  The viewpoint in Yokohama is from right under Jupiter to the neighborhood of
  the central three stars of Orion. I examined it to here, but the observation
  seems to be impossible because the weather of Yokohama will be rain tomorrow.

  but not confirmed. At it was just before dawn,
  other satellites were also bright by sunlit. (English) (Japan)

[FITSAT-1 Flashing Plan]

  We have learned through the experiments of flashing NIWAKA:
  1. The night sky must be dark enough to see the milky way.
  2. Photos successfully used around F4, 400mm lens and ISO12800 camera.
  3. Most people noticed their success after took photo and magnified.
     This means the camera must be turned to the accurate direction, and
     shuttered at exact time. Multiple shutters will be useful.
  4. The green beam always turn to the magnetic north, and the red beam
     turn to the magnetic south, so the beams do not turn to the ground
     around the equator. In order to observe the light, higher latitude 
     will be good result.

  As observing the light is not so easy, we will flash the light on
  request. If you have a plan for observing the light, please advice me
  the time and date with your latitude and longitude. Now we have a plan
  for flashing at 09:25:00 on 9th Feb. for the west coast of USA.
  (Time will be changed by the latest TLE.)
