What's That Moving Across the Sun?

It had been cloudy and raining most of the time in the past 2 weeks. Finally the skies cleared up on Saturday 15 Oct 11. Numerous sunspots have formed on the solar disk many of which are pointing towards Earth. Prominences and filaments are also clearly displayed. These solar activities are the usual observations on my DMK 41AU02.AS. Today, something else unusual was observed. As I went over my first video recording, I noticed a black dot moving across the top half of the solar disk. It took about 29 seconds to move across the solar disk. Checks with several sources were not successful in identifying the object. It would be interesting to know what it was. The recording was done on October 15th, 2011, 08:59 UTC from Singapore.
