409E-450-Saint Patrick's Day Comet
Tuesday, 6 October, 2026
On Saint Patrick's Day, while searching for Earth approaching asteroids with the Catalina Sky Survey's 60 inch telescope on Mt. Lemmon, Arizona I spotted a slightly enlarged star like object with a tiny tail moving through the constellation of Virgo. After checking to see that it was not a known comet, I sent my discovery observations along with a description of it's coma and tail to the Minor Planet Center. Turns out that it had been observed as a moving point of light, but not noticed to be a comet, by the PanSTARRS group in Hawaii 3 month's earlier. Given the PanSTARRS historical observations along with those from other observatories around the world it only took scientists at the Minor Planet Center 2 days of additional observations to verify it to be a newly discovered comet. Since the naming rules state that a comet should be named after the first observer that identified it to be a comet it was given the C/2018 F1 (Grauer). In December of 2018 and July of 2019 Comet C/2018 F1 (Grauer), which I share with my wife Annie Grauer, will be closest to Earth on it's 5,555 year orbital path about our Sun. Unfortunately it is not likely to be visible to the unaided eye, appearing only as faint moving comet in the night sky on electronic camera images, leaving us to speculate on the condition of humanity when Comet C/2018 F1 (Grauer) returns in the year 7573 AD.
