Comet Lovejoy survives perihelion! | |
Anonymous Coward User ID: 1578009 United States 12/15/2011 11:45 AM Report Abusive Post Report Copyright Violation | I've been looking all over, and likely missed it, but.... When exactly is perihelion? Is it today, the 15th, at 7:00pm EST? I'm tired of looking and not finding the answer. Quoting: Wotansdottir Thanks! Whoops, of course I find it right after asking. this is the prediction.. Quoting: RTS REDUX [...]Astronomer Gareth V. Williams computed a preliminary orbit for the comet, which indicates that perihelion (closest approach to the sun) will occur at 7 p.m. EST Dec. 15 (00:00 GMT on Dec. 16) at a distance of 548,000 miles (882,000 km) from the center of the sun, meaning that the comet will skim a mere 115,000 miles (186,000 km) above the solar surface, putting it into the special classification of a "Kreutz Sungrazer."

Quoting: Anonymous Coward 7160652 I live in the EST time zone. Also which direction to look. Thank you very much, really cool thread and I hope I have a chance to see this and have a few beers. Thanks again folks Someone told me to look left of the sun at sunset Supposedly 7pm est will be the Graze/hit which will be too late for us :( Oldmotherhubbardglp (at) live.com ~mistakes are proof that you are trying~ ~be kind to unkind people, for they are the ones that need it the most~ |

Thanks its dark here now :) but could we see anything? Not unless it manages to survive perihelion, and even then, not right now. The only way you or I will see it for the next several hours is through the various sun-watching satellites. |
