Astronomy enthusiasts in Orihuela Costa will soon have a unique chance to witness a once-in-a-lifetime celestial event: the arrival of Comet Tsuchinshan-ATLAS (C/2023 A3). This bright comet is expected to light up the skies during its closest approach in late September to early October 2024, and the Costa Blanca’s favorable Mediterranean location offers a great vantage point for stargazing.
A Brief Overview of Comet Tsuchinshan-ATLAS
Comet Tsuchinshan-ATLAS was discovered in early 2023 by a collaboration between the Tsuchinshan Observatory in China and the ATLAS (Asteroid Terrestrial-impact Last Alert System) survey. This long-period comet originates from the distant Oort Cloud, located at the edge of our solar system. The comet’s trajectory is expected to bring it close enough to Earth in late September 2024 for it to become visible to the naked eye, depending on its brightness.
When Can You See the Comet from Orihuela Costa?
From Orihuela Costa, the best time to view Comet Tsuchinshan-ATLAS will be during its peak period, late September to early October 2024. During this time, the comet will be visible in the early evening sky after sunset.
Viewing Window: Late September to early October 2024
Best Times: Just after sunset, when the sky darkens, and the comet is high enough above the horizon to be easily visible
Direction: Look to the western and northwestern parts of the sky, as the comet will be heading towards the Sun on its inbound journey.
Best Locations for Viewing in Orihuela Costa
While Orihuela Costa itself is a beautiful coastal region, light pollution from urban areas can interfere with the clarity of the night sky. However, there are plenty of excellent nearby locations where you can escape the city lights and enjoy a clearer view of Comet Tsuchinshan-ATLAS.
Here are some of the top spots in the Costa Blanca area for stargazing:
1. Campoamor Beach and La Zenia Beach
These popular beaches in Orihuela Costa are great for a casual night of comet watching. While there may still be some light pollution from nearby resorts, heading out onto the sand, away from the town, gives a clear horizon view. Pack a blanket and find a quiet spot on the beach where you can watch the sunset and stay until the sky darkens.
2. Sierra de Orihuela
For a darker sky and higher elevation, the Sierra de Orihuela mountain range, located just a short drive inland, offers an excellent stargazing location. The Sierra’s hills and valleys provide natural protection from the glow of nearby towns, making it easier to spot fainter celestial objects like comets.
3. Cabo Roig Viewpoint
Located at Cabo Roig, this popular clifftop offers panoramic views of the Mediterranean. While it’s a more touristy area, you can still find quiet spots along the coast to watch the sky, especially if you head there after sunset. The open view toward the horizon will allow you to see the comet as it rises.
4. La Pedrera Reservoir (Embalse de La Pedrera)
Just 20 kilometers inland from Orihuela Costa, La Pedrera Reservoir offers expansive, dark skies away from the coast’s bright lights. The area around the reservoir is much less populated, so you’ll experience clearer skies and less interference, making this a fantastic location for comet viewing.
5. Cañada de Alhama Natural Area
Situated between Orihuela and Murcia, the Cañada de Alhama nature reserve is another great inland destination. This remote area is known for its clear skies and minimal light pollution, providing an ideal backdrop for celestial events. Bring binoculars or a small telescope for an enhanced view of the comet.
6. Sierra Escalona Natural Park
A lesser-known natural reserve, Sierra Escalona, located a little further inland from Orihuela Costa, offers excellent conditions for stargazing. The park’s high elevation and distance from urban areas mean darker skies, perfect for spotting a comet.
How to Maximise Your Viewing Experience
Get Away from Light Pollution: While Orihuela Costa’s urban lights may reduce visibility, a short trip inland to natural areas or along the coast will significantly improve your chances of seeing the comet in all its glory. Prioritize locations with minimal artificial lighting.
Use Binoculars or a Telescope: While Comet Tsuchinshan-ATLAS may be visible to the naked eye, bringing binoculars or a small telescope can give you a closer look at its tail and the details of its glowing nucleus.
Monitor Sky Conditions: September and October often bring pleasant weather to the Costa Blanca, but it’s essential to check the local forecast for cloud cover. Clear skies will give you the best possible view of the comet.
Join Local Astronomy Groups: If you want to take your viewing to the next level, consider connecting with local astronomy groups in the Costa Blanca region. These groups often organize stargazing events and may have access to high-powered telescopes for a more detailed look at the comet.
The Perfect Stargazing Getaway
For residents and visitors in Orihuela Costa and the wider Costa Blanca, Comet Tsuchinshan-ATLAS provides a perfect excuse to explore the beautiful landscapes of this region at night. Whether you’re watching from the coastal cliffs, mountain ranges, or peaceful inland reserves, this comet is set to offer a breathtaking celestial spectacle, making September 2024 a month to remember.
Mark your calendars, grab your binoculars, and head out to one of these stunning locations in Orihuela Costa for a truly unforgettable encounter with one of the universe’s great travellers.
