Partial Solar Eclipse Observation

| Monday, January 26, 2009


As most people know, today is when then partial solar eclipse occur. Since I am in Kuala Lumpur, the process started at approximately 4:31:32 pm, mid-eclipse at 5:50:42 pm and ended at 6:58:55 pm.

The Geometry of Solar Eclipse

Partial Solar Eclipse at Kuala Lumpur - Coverage 64.1%

Viewing the sun without safety filters can cause a permanent eye damage or blindness. Since I did not get myself an appropriate visual aid like the solar eclipse viewer or anything, I improvised by doing some research on the internet on alternative to view this magnificent moment.

And so I made a backyard science project on safe way to view. These are the steps I followed...

1. Prepare a piece of white cardboard, a piece of aluminium foil, a pin, a sheet of white paper, masking tape, penknife, scissors, ruler and pencil.

2. Cut an opening on the cardboard.

3. Tape a piece of aluminium foil over the square using masking tape.

4. Make a pinhole in the middle of the foil.
5. With the Sun behind you, hold the pinhole cardboard as far away from the white cardboard.
6. The farther you are from the screen, the larger image will be produce.

After following the instruction really carefully and improvising the techniques based on the available is the end product...

These are some of the images captured during the solar eclipse

p.s : It was fun because you don't always do this kinda stuff. Hehe
