India to witness a rare and mesmerising DOUBLE meteor shower on July 30!

As the monsoon rains refreshes India while the nation cheers on its athletes in the ongoing Olympics, the skies above promise another natural spectacle that will captivate stargazers. This month, India will witness a rare celestial event: a "double" meteor shower featuring both the Alpha Capricornids and the Southern Delta Aquariids, peaking within 24 hours of each other.

Meteor showers occur when Earth’s orbit intersects the path of a comet, causing rocky debris to burn up in our atmosphere. This month, Earth will pass through the orbits of comet 96P/Machholz and comet 169P/NEAT, giving rise to the Southern Delta Aquariids and Alpha Capricornids respectively. The Southern Delta Aquariids will peak on July 29-30, while the Alpha Capricornids will peak on July 30-31.

Nicholas Moskovitz, a planetary astronomer at Lowell Observatory, notes that such close peaks of two meteor showers are "a little bit unusual" but not entirely uncommon. Observing them helps scientists understand comet behaviours and predict future meteor showers, which is crucial for the safety of spacecraft.

Visibility in India

Both meteor showers are expected to be visible in India, particularly in the southern regions and areas away from urban light pollution. For the best viewing experience, find a dark site, ideally in rural areas or hill stations. The Southern Delta Aquariids will produce around 20-25 meteors per hour at their peak, appearing as faint streaks that require dark skies to be seen. The Alpha Capricornids, while less frequent at about 5 meteors per hour, are known for their bright fireballs, making them more spectacular even in less than ideal conditions.
To catch these celestial wonders, it’s recommended to watch the sky between midnight and dawn. Make sure to find a dark spot away from city lights, stay off devices to allow your eyes to acclimate to the dark. Be patient, lie back and scan the sky, focusing on areas away from the moon. It would also be wise to check the local weather forecast to ensure clear skies before heading out for any stargazing.

Both showers will be most visible if you look towards the southern horizon. The meteors will appear to radiate from the constellations Aquarius (for the Southern Delta Aquariids) and Capricornus (for the Alpha Capricornids), but you should look away from these radiant points to see longer meteors streaking across the sky.
So, mark your calendars, prepare your night-sky essentials, and get ready to witness a double meteor shower that promises to be a highlight of the monsoon season. As athletes from around the globe compete for glory, the night sky will provide a universal display of nature's own fireworks.
