Marcel de Bont Posted November 21, 2013 Share Posted November 21, 2013 Put it in your agenda: today in exactly a week (November 28th) comet C/2012 S1 (ISON) will fly past the Sun and the Solar Dynamics Observatory (SDO) will be there to capture it! The SDO science team will point the spacecraft away from the Sun at three predefined points (approach, perihelion, departure) to give us the best view on comet ISON as it moves through perihelion. The Sun will still be in the frame but only partially. Perihelion (when ISON will be at it's nearest to the Sun) will occur at 18:44 UTC on November 28th. About 100 minutes before perihelion, SDO will be pointed at the “Approach†position. It takes about 5 minutes to point and settle the spacecraft to show different location. Every position will then be observed for 1 hour, followed by 5 minutes of ''move & settle'' time. At 20:19 UTC, SDO will point back to the Sun and ISON will be on it's way to fly out of the solar system. In the animation below you will see where SDO will be pointed as ISON flies past the Sun. The NASA/SDO science team tested these maneuvers on November 6th with success. https://www.facebook.com/photo.php?v=549719835114941 Footage and information courtesy of NASA/SDO, HMI, and AIA science teams.

Guest lingduxingxi Posted November 27, 2013 Share Posted November 27, 2013 SOHO-LASCO C3-ISON CME-Whether it will affect the comet? Link to comment Share on other sites More sharing options...
Marcel de Bont Posted November 27, 2013 Author Share Posted November 27, 2013 The CME was produced by a filament eruption. It looks like the CME might indeed hit the comet. Going to be interesting to see what will happen. It could loose it's tail for a moment. Link to comment Share on other sites More sharing options...
Guest lorendesmc Posted November 28, 2013 Share Posted November 28, 2013 Bonjour à tous, pourquoi le soleil est il si calme ? ses éruptions de début novembre nous laissaient croire à un possible réveil mais il n'est rien à ce jour. Ison interagit très peu avec lui et nous laisse penser que cette comète va continuer son bout de chemin.. Merci aux commentaires que vous laissez sur ce site que je trouve très intéressant.

Vancanneyt Sander Posted November 28, 2013 Share Posted November 28, 2013 l'activité de la soleil est calme mais c'est normal, aussi au maximum on peut avoir des moments avec moins d'activité.ISON est en beau course, le moment suprême est presque la, j'espère qu'il survit.
