Silolona Sojourns has released its calendar of astrotourism-focused sailings for 2026, highlighting key celestial events visible from its two phinisi yachts, Silolona and Si Datu Bua. Operating in remote areas of Indonesia with minimal light pollution, the yachts provide clear conditions for night sky viewing at sea.
Astrotourism, which focuses on travel linked to night skies and celestial events, is expected to grow in 2026, with several major events visible during the year.
A total lunar eclipse will occur on March 3, 2026, with the moon fully obscured for 58 minutes. The full event is expected to last more than five hours, beginning around 18.30. The Lyrid meteor shower is forecast to peak on the night of April 21, with viewing conditions strongest after midnight until before dawn, when 10 to 15 meteors per hour may be visible. The Perseids meteor shower is expected to peak between August 11 and August 13, with up to 100 meteors per hour. Guests travelling between October and April may also see the Milky Way while sailing through Raja Ampat, a region known for dark skies.
Silolona Sojourns also offers night diving on all charters for certified divers. Night dives are available across destinations including Flores, Alor, Raja Ampat, Banda and Cenderawasih Bay. Divers may encounter bioluminescent plankton and a range of marine species that are more active after dark.
Both vessels feature open deck spaces for stargazing, including a bow lounge area positioned close to the water. Crew members are available throughout the night to support guest activities.
Private charters on Silolona are priced from US$18,700 per day, sleeping up to 12 guests. Si Datu Bua charters are priced from US$12,000 per day, sleeping up to six guests.
Rates include accommodation, meals, diving and scheduled activities, excluding tax.
