Double shadow transit of Jupiter

[universe24]

Hi all,

After taking Jupiter images many times, there is one phenomena that will happen on Jupiter but I never take it before. That is double shadow transit on Jupiter surface.
After wait for a year long, I missed twice of the double shadow transit events due to bad weather. Luckyly, on 08June2005, Wed, I finally got it and recorded the event. The most happy thing is the shadow is "made" by Europa & Ganymede which can be consider as rare phenomena. This is because usually will be Io & Europa make the shadow more often.
Below is the images taken. Comments are welcome.

biasanya fenomena ini berlaku berapa tahun sekali?...

dan, apa yg menyebabkan ia berlaku?...

[universe24]

Sebenarnya, fenomena ini boleh berlaku bila bila masa. Yang penting mesti lihat bagaimana satelit-satelit Jupiter itu beredar mengeliligi Jupiter. Kalau timing betul, then berlakulah fenomena ini. Tahun ini, saya telah miss 2 kali fenomena ini. Yang gambar atas tu pula lucky saya untuk tangkap fenomena ini.
Fenomena ini berlaku apabila satelit Jupiter beredar di hadapan Jupiter.Pancaran cahaya matahari ke atas satelit akan menjadi satu bayang ke atas permukaan Jupiter.
