Today's 2 topics:
- The National Oceanic and Atmospheric Administration has published an extensive data based review, analysis, and summary of the Earth's Climate. 2016 was hotter than 2015 which was hotter than 2014. 2016 is the warmest year the Earth has been in the more than 180 years of record keeping. Overall in 2016 the whole Earth was 1.8 F above the 1951-1980 average. The Arctic in 2016 was 7.2F higher than it was the pre-industrial age.
- Carson Fuls was using the new hundred million pixel camera on our team's Schmidt telescope located on Mt. Bigelow, Arizona, when he discovered 2017 AG13. It passes near the Earth's orbit twice a year on its own 345 day path around the Sun. When Carson spotted it, 9 lunar distances from him it was heading in our direction at about nine and a half miles per second. Three days later it came to less than two times the distance the Moon's distance from us. Less than three weeks later Carson was using the same equipment when he discovered another small space rock, 2017 BH30, which came to a bit more than an Earth's circumference from our home planet.
