STIME DI MAGNITUDINE DEL 2005
Qui di seguito sono riportate misure fotometriche di comete, fatte da osservatori italiani. Il formato usato è quello dell'IAUC, con ulteriori indicazioni nell'area dedicata alle note. Normalmente le misure fatte con il ccd possono differire da quelle fatte visualmente anche di una o più magnitudini, questo per il diverso campo utilizzato e per la diversa sensibilità spettrale dei ccd e dell'occhio umano. Per le misure fatte con il ccd si è deciso, all'interno del Gruppo Osservatori Comete, di utilizzare un'apertura pari ad un diametro di 100.000 Km di chioma o suoi sottomultipli, calcolabile con l'espressione : A"=122,3/Dist , dove la distanza è quella della cometa rispetto alla Terra, in U.A, al momento della ripresa.
Here following measures fotometriche of comets is brought, served as Italian observatories. The used format is that of the IAUC, with further indications in the area devoted to the notes. The measures done with the ccd can normally differ also visually from those sorts of one or more magnitudes, this for the different used field and for the different ghostly sensibility of the ccds and the human eye. For the measures done with the ccd you/he/she is decided, inside the Group Observatories Comets, to use an equal opening to a diameter of 100.000 Kms of head of hair or his/her sottomultiplis, calculable with the expression: A"=122,3/Dist, where the distance is that of the comet in comparison to the Earth, in U.A, during the photo.
