Comet ISON Grand Entrance to meet CMEs!!

Comet ISON has joined Comet Encke in the field of view of HI-1A (STEREO-A Heliospheric Imager 1). As seen from the spacecraft they are going to get very close to each other, but they are not going to collide because the two comets are actually millions of miles can be seen coming towards the two comets, but there seems to be no major interaction designated C/2012 S1 (ISON), it was discovered by Vitali Nevski and Artyom Novichonok, of the International Scientific Optical Network (ISON) in Russia, on September 21, 2012. The discovery was announced by the Minor Planet Center on 24 will come to perihelion at a distance of AU (1,860,000 km; 1,150,000 mi) from the center point of the Sun. Accounting for the solar radius of 695,500 km (432,200 mi), ISON will pass approximately 1,165,000 km (724,000 mi) above the Sun's to NASA, during the last week of its inbound trip, ISON will enter the fields of view of several NASA Heliophysics observatories. NASA's Heliospheric Imager on board STEREO (Solar Terrestrial Relations Observatory) will be the first to view ISON, followed by observations from coronagraphs which will be coming from STEREO and the joint European Space Agency/NASA Solar and Heliospheric Observatory, or SOHO. After that, NASA's Solar Dynamics Observatory (SDO), will view the comet for a few hours during its closest approach to the sun. The X-Ray Telescope on the JAXA/NASA Hinode mission will also be looking at Comet ISON for about 55 minutes during perihelion (closest approach to the Sun).The dates of viewings by these observatories are as follows: Nov 21-28: STEREO-A Heliospheric Imager Nov 26-29: STEREO-B coronagraphs Nov 27-30: SOHO coronagraphs Nov 28-29: STEREO-A coronagraphs Nov 28: SDO Nov 28: #.UpG82ijfZzpTry out an interactive model dedicated to Comet ISON the latest updates, visit the following sites: and observations +S1&page=6&utf8=Related sites: -- ISON and : NASA/STEREO/SECCHIThe Path of Comet spacecraft credit: Alex LutkusSDO spacecraft Spacecraft image:: Eureka - YouTube Audio Library Microchip - YouTube Audio LibraryCredit: STEREO/SECCHI/NASA/NRL NASA's Goddard Space Flight Center NASA
