TECHNICAL SPEECH ON ANNULAR ECLIPSE

We KRMC, strive to educate the students and remove the superstitions from society, on the eve of "ANNULAR SOLAR ECLIPSE" we tried our best to do ourselves, we went to Zilla Parshid High school, Epurpalem and gave the technical and exact meaning of the eclipses and tried to eradicate the beliefs.

To experience the Solar eclipse we bought " Filter glasses " and went for school, we gave the technical aspects of briefing into "Introduction to Astronomy" how the eclipses are formed? , the reasons behind it, and the other aspects of space science and technology, The seminar is taken by Founder and Baaji, an enthusiast keen into space science and trying his best to educate upcoming students.

Annular Means Ring-Shaped

The name “annular” comes from the Latin word for ring, “annulus.” These eclipses are named for their darkest, or maximum, point even if it only lasts less than a second. If the characteristic ring of fire is visible from even just one location, the whole eclipse is called an annular solar eclipse.

However, in most places and for most of the duration, an annular eclipse looks like a partial solar eclipse. This is also the case for total solar eclipses and for the rare hybrid solar eclipses which have an annular maximum point in some locations and a total maximum point in other locations.

When Do They Happen?

Annular solar eclipses can only take place when:

1.       It is the New Moon.

1.       At the same time, the Moon is at (or very near) a lunar node, so the Earth, the Moon, and the Sun are aligned in a straight (or nearly straight) line.

1.       The Moon is near its farthest point from Earth, called apogee, so the outer edge of the Sun remains visible as a ring of sunlight.

1. Why Not Every New Moon?

Solar eclipses are relatively rare. For any solar eclipse to take place, it has to be around New Moon, when the Sun and Earth are aligned on opposite sides of the Moon. Normally, the New Moon is invisible from Earth. The only time we can see it is during solar eclipses, silhouetted against the Sun.

2. Close to Lunar Nodes

 So why isn't there an eclipse every night there is a New Moon? This is because the New Moon also has to be close to a lunar node.

The plane of the Moon's orbital path around Earth is inclined at an angle of approximately 5° about Earth's orbital plane around the Sun—the ecliptic. The points where the 2 orbital planes meet are called lunar nodes. When the Sun and the Moon are close enough to a lunar node to form a perfect or almost perfect line with Earth, we are in the eclipse season, which lasts around 34.5 days. In every eclipse season, there are 2 to 3 eclipses, and at least 1 of these is always a solar eclipse; at the most 2.

3. Moon Is Far from Earth

Throughout every lunar month, the distance between our planet and the Moon varies because the shape of the Moon's orbit around Earth is elliptical, rather than circular.

The reason we can see the glowing outer edge of the Sun at the maximum point of an annular eclipse is that it happens while the Moon is near its the farthest point from Earth, called apogee, when the Moon is smaller than the Sun when viewed from Earth.

Students watching Annular solar eclipse

After the technical seminar, we provided Filter glasses and given the instructions, how to use and what the preventive methods, Finally, at last, we had the chance of brainstorming session on Eclipses and Astronomy, where a lot many questions arose, Dr. Varaprasad and Baaji cleared those doubts for both students and as well as the teachers.

I wish all the best to students and I am grateful to the staff of the school who supported us.

Special thanks to every one of my team.

Thank you for your support, Stay tuned
