WHAT ALL YOU CAN DO WHILE WATCHING ANNULAR SOLAR ECLIPSE?
Eclipses are beautiful, spectacular natural celestial phenomena that do not happen every day. Also, if you miss the opportunity to observe the annular solar eclipse of 21 June 2020, the next annular eclipse you will be able to view from India is in 2031, i.e., almost after 10 years. Therefore, the upcoming ASE becomes a must-watch event. Besides viewing eclipses one can also
perform some experiments at the time of the eclipse. Following experiments can be performed at your home during the ASE.

Aim:
Finding the duration of an eclipse and its maximum phase by projection of the Sun
Apparatus/Materials Required:
Ball mirror, ruler and digital clock.
Procedure:
1. Project the image of the Sun with help of a ball mirror on a wall as shown in Figure 1.
2. Keep the distance between the ball mirror and wall approximately 20 to 30m.
3. After projecting the Sun, you can see the different phases of the eclipse as shown in Figure 2 and Figure 3.
4. Keep track of the projected image and note the timings with the help of digital clock in the observation table.
