Super Worm Equinox Moon
- The last supermoon of the year has coincided with the Spring Equinox. The phenomenon is generally known as ‘Super Worm Equinox Moon’.
- The full moon of the March is the third supermoon of the year, following a super blood wolf moon on January 21st and a super snow moon on February 19th.
- The full moon is also known as the worm moon in some parts of the world. It is called so because, in cold climates, the ground begins to warm up at this point and earthworms appear.
- When the moon is at its closest point to the earth, it is called ‘perigee’ and when a full moon coincides with a perigee, it is called Supermoon.
- The Equinox is the moment when the length of day and night become equal and the sun’s rays fall directly on the earth’s equator. The phenomenon happens twice a year– once as autumn equinox in September and the other in March as spring equinox or vernal equinox.
- The LightSail 2 is a project to demonstrate controlled solar sailing using a miniature CubeSat satellite.
- It will be launched from the Kennedy Space Center, Florida, US in April 2019.
- LightSail 2 is the second of three satellites built to demonstrate the feasibility of powering a spacecraft using solar radiation.
- This mission is designed to see if LightSail can move into higher orbits around the Earth using only photons from the sun to push it along.
- Solar sails (also called light sails or photon sails) are a proposed method of spacecraft propulsion using radiation pressure exerted by sunlight on large mirrors.
- ‘Fall armyworms’ are native to the Americas but they have been moving eastwards since 2016, sweeping across Africa, where they caused $1-3 billion in damage, before arriving in Asia.

- FAO meeting in Bangkok with officials from affected countries and experts for discussing ways to limit armyworm infestations amid a “growing sense of alarm”.
- FAO is working with local authorities and training farmers to manage the pests by crushing egg masses and using biopesticides.
- Chemical pesticides are an option but should be carefully considered due to environmental and health damages.
Food and Agriculture Organization (FAO)
