![]() ![]() After an asteroid is identified on Maui and appears to be passing close to Earth, telescopes on Maunakea and elsewhere will stop what they are working on and track the object to determine if it is a possible threat.Ĭloser analysis of the meteor cluster is underway and more in-depth information will be published.įor more information, go to the Subaru Telescope website.The first telescope built atop Mauna Kea was tiny by today’s standards, an 88-inch instrument that astronomers hoped would reveal new details about the universe, and draw the world’s best researchers to a mountain relatively unknown in the scientific community. IfA-run telescopes ATLAS and Pan-STARRS on Haleakalā specialize in the detection of potentially hazardous asteroids. Hawaiʻi astronomy plays a vital role in the nation’s planetary defense system. “It’s exciting that we have more ‘eyes on the sky’ that are able to capture these very short-lived events.” Hawaiʻi leads in near-Earth object detectionĬollaboration between observatories on Maunakea and Haleakalā is crucial. “These meteor clusters come from larger parent bodies like asteroids or comets so they can tell us more about the compositions of those larger objects,” said Larry Denneau, an ATLAS project scientist. The event was captured by its all-sky camera. Subaru reached out to astronomers at the UH ATLAS (Asteroid Terrestrial-impact Last Alert System) telescope on Haleakalā to see if the cluster was also detected. The University of Hawaiʻi Institute for Astronomy hosts the AMOS systems, which are operated by Comenius University in Bratislava, Slovakia, and are used for observations and analysis of meteors and fireballs. The AMOS data, when examined by astronomers, suggests that the cluster was caused by fragments of a fragile Halley-type comet.

A meteoroid cluster is thought to be caused by meteoric material breaking up into smaller pieces shortly before entering Earth’s atmosphere. Astronomers from Subaru’s 8.2-meter telescope describe the non-hazardous event as a rare meteor outburst associated with a “meteoroid cluster.” Only a few cases have been reported since the phenomenon was first identified during the Leonid meteor shower in 1997. The Subaru-Asahi Sky Camera atop Maunakea captured more than a dozen meteors streaming from the same direction within a 10-second window.Īvid viewers online were mesmerized, unsure of what the head-turning sight actually was.
