C-2014 E2

E' la seconda cometa scoperta quest' anno -attraverso le immagini catturate con CCD aa su telescopio riflettore da 45 cm a montatura equatoriale con F/2,9- da Jacques ed i suoi amici-colleghi

Eduardo Pimentel e Joao Ribeiro de Barros,

dopo la C/2014 A4 (SoNear) nel mese di gennaio.

Avvistata con una magnitudine di 14,7 nella parte settentrionale della costellazione del Centauro, nelle notti successive si è spostata cavalcando il confine della costellazione dell'Idra.

Si tratta di una cometa non periodica, dall'orbita parabolica con inclinazione di circa 156° e valore di eccentricità 1. All' osservazione mostra una chioma di 2 arco minuti,

l' atmosfera cometaria risulta densa, fitta, abbastanza brillante, e presenta anche una breve coda. Avanzare stime sulla sua luminosità è stato difficile, ma pare che l' oggetto possa presto giungere

ad una magnitudine compresa tra 12 e 11, infatti nelle prossime settimane si avvicinerà sempre più alla Terra ed al Sole, e ciò incrementerà la sua attività e quindi luminosità.

Con una velocità relativa al Sole di 31,358 Km/sec ha raggiunto il perielio il 2 luglio 2014 passando a circa 9 milioni di chilometri dal Sole, pochi giorni dopo ha effettuato un passaggio su Venere :

secondo l' orbita calcolata, il 13 luglio è transitata a circa 0,088 UA (circa 13,1 milioni di chilometri) dal pianeta, sarebbe stato uno spettacolo poterla ammirare da una distanza tale per noi sulla Terra!

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
