Description: C/2013 A1 (Siding Spring) is an Oort cloud comet discovered on 3 January 2013 by Robert H. McNaught at Siding Spring Observatory using the 0.5-meter (20 in) Uppsala Southern Schmidt Telescope.[1'> At the time of discovery it was 7.2 AU from the Sun and located in the constellation Lepus. Comet C/2013 A1 probably took millions of years to come from the Oort cloud. After leaving the planetary region of the Solar System, the post-perihelion orbital period (epoch 2050) is estimated to be roughly 1 million years.[3'> Precovery images by the Catalina Sky Survey from 8 December 2012 were quickly found.[1'> On 3 March 2013, Pan-STARRS precovery images from 4 October 2012 were announced that extended the observation arc to 148 Facebook Live Quake Data https://www.facebook.com/EarthquakeHunter Downloadable PDF June Newsletter Link: http://www.solarwatcher.net/index.php%3Foption%3Dcom_mediashop%26view%3Dsimpleitem%26Itemid%3D77 Facebook Live Quake Data https://www.facebook.com/EarthquakeHunter http://solarwatcher.net Earthquake Forecasting Channel http://youtube.com/thebarcaroller Earthquake Reporting Channel http://www.youtube.com/user/EQForecaster Soho Website http://sohowww.nascom.nasa.gov/ Solar Soft website http://www.lmsal.com/solarsoft/latest...
