    905-Hogan’s Interesting PHA
    2026/06/26
    My Catalina Sky Survey teammate Josh Hogan has discovered a 2 football field diameter asteroid that was placed on NASA’s Sentry list because it has a tiny minuscule but non-zero chance of impacting our home planet. With this motivation my team the Catalina Sky Survey, the Pan STARRS group in Hawaii, the ATLAS group with telescopes Hawaii, Chile, and South Africa , the Vera C. Rubin telescope in Chile, will be soon joined NASA’s NEO Surveyor and groups world wide in a planet wide defense network.

    Asteroids appear as moving points of light in an asteroid hunter's images so that when my Catalina Sky Survey teammate Alex Gibbs spotted a fuzzy moving object he immediately suspected it to be a comet. The data obtained by astronomers over the next 8 days enabled scientists at the Minor Planet Center to verify Alex's 31st comet discovery and give it the name C/2018 A6 (Gibbs). In January of 2018 it was in the constellation of Leo traveling from the vast empty space above the Sun's north pole toward the plane of the solar system which contains all of the planets and most of the asteroids. In March of 2018 Comet C/2018 A6 (Gibbs) will cross the plane of the solar system a bit farther from the Sun than the giant planet Jupiter's orbit. After that it will continue on a wide arcing parabolic path, pass under the Sun's south pole in the summer of 2019, and once again cross the plane of the solar system in February of 2021. After that it will continue into the vast empty space above the Sun's north pole from whence it came. How a comet brightens as it approaches the Sun is difficult to predict. With luck humans will be able to spot Comet C/2018 A6 (Gibbs) with their naked eye, binoculars, or a small telescope as it pays a rare visit to our planet's neighborhood.

    904-Ohio Fireball
    2026/06/19
    On St. Patrick’s day 2026 a fireball meteor brighter than the full moon streaked across the daytime sky. The American Meteor Society received 223 eyewitness reports from observers in 15 states, the District of Columbia, and Ontario Canada as well as 5 videos and 6 photos. NASA reported that the incoming object was approximately 6 feet in diameter, weighed about 7 tons, released the energy of 250 tons of TNT, created a sonic boom heard over a wide area , and rained bits of itself onto the ground in Medina county Ohio.
