Seismologists in Cuba have tentatively attributed mysterious lights illuminating the night sky above the Moa seismological station in the country's east to a meteorite.
At 10:06 pm, the station registered 'several luminous phenomena', with residents in multiple communities reporting spotting a red and white light followed by one or more explosions.
National Seismological Service Chief Enrique Arango Arias confirmed to CubaDebate that the agency believes the event was caused by a space rock.
The fireball began at an altitude of about 100 km over the province of Jaén (Andalusia), and ended at a height of around 52 km over the province of Ciudad Real (Castilla-La Mancha). This meteor was recorded in the framework of the SMART project, operated by the Southwestern Europe Meteor Network (SWEMN) from the meteor-observing stations located at Sevilla, La Hita (Toledo), Sierra Nevada, La Sagra (Granada), Calar Alto ( Almería), and Madrid (UCM, Jaime Izquierdo).
The event has been analyzed by the principal investigator of the SMART project: Dr. Jose M. Madiedo, from the Institute of Astrophysics of Andalusia (IAA-CSIC).6:07(Spanish peninsular local time) of March 17.

Residents of Gorontalo Province who saw the meteor said that they heard a loud boom sound when the meteor lights up the night sky. Some experts believe that the flying object was a bolide, a very bright meteor.

New simulations have identified the Karma family of asteroids in the main belt as a potential source of near-Earth asteroids.
When asteroids in the main belt of the solar system collide, the fragments come back together to form smaller rubble-pile bodies that orbit the Sun as a "family." Under the right conditions, some of those family members can end up in near-Earth space.
In a study published in Monthly Notices of the Royal Astronomical Society, researchers simulated the orbital evolution of asteroids in the Karma family, starting with the initial family-creating impact. The results suggest that over the family's lifetime, 350 members have transferred close to Earth's orbit — and around 10 might currently be in near-Earth space right now.

Eyewitnesses posted about the phenomenon that was observed shortly after 3 a.m. on Sunday across the Kanto region, which includes Tokyo.
A video taken by an NHK camera in the capital's Shinjuku Ward shows a ball of light streaking from the upper middle of the screen to the lower left.
Another NHK camera in Tokyo's Chuo Ward captured similar footage, and the light is seen reflected on the surface of water.
