My Other Interest : Iridium Flares & other Satellite Observation

Every evening and early morning hundreds of satellites pass over Singapore. Of these at least a handful is bright enough to be seen with the naked eye. The positions and timings of these appearances can be easily obtained from prediction services or DIY predictions using widely available from the web.
These satellites appear as bright dots (very star- like) of light that move across the sky. The brightest satellites seen in Singapore sky are around 0.0 ~ 2+ magnitude. Of notably exception is Iridium flare (reflected sunlight from door-size MMA module) which can easily outshine Venus. The brighest Iridium Flare seen here is magnitude -7 making it the second brightest object in the sky after our moon. Typical flares last 5-10 seconds. What attract me to this new hobby is the highly predictable flare occurrence (within seconds of prediction). The skill sets acquired in sky-watcher come into handy for satellite observation and tracking.

You do not need any special dark sky to enjoy Bright Iridium Flares - I have observed flares in downtown Orchard - not far from Orchard MRT Station, and also minutes after I disembark from Yishun MRT station in time to view the double flares besides the overhead Railtracks! I have also seen flares where not even a single star is visible (worst Limiting magnitude).
