ZZ-ZZ-ZZ-FN-Earthshine.gifCoronal Mass Ejection and Earthsine124 visiteThis photograph was taken by Devgun Chander of Sohna, Haryana, of India. It shows a striking clarity to the earthshine region of the Moon. When I first look at the photograph I was impressed that Aristarchus was standing out so bright even though it very close to the sunset terminator. I sent the photograph to Dr. Anthony Cook the senior recorder for the L.T.P. sections of BAA and ALPO. He sent me the measured brightness of specific lunar formations and of the Lunar Maria.
(...) The Maria across the face of the Moon is uniformly bright except for the formations Mare Humorum, Mare Frigoris and Maria located near Aristarchus. Dr. Anthony Cook believes they are brighter due to the glare from the nearby sunset terminator. (...) The fact that we had a significant coronal mass ejections into space or CME take place on November 8-9,2004 causing aurora reports all over the World. If Solar Excitation is a factor for the extreme brightness of the Earthshine this would be the event to cause it.

Kane Crater - Light Ray (2).jpgLight rays inside Kane Crater (2)124 visiteUn commento si impone: il lavoro dell'Amico Robert Spellman davvero notevole e, a dispetto di seeings talvolta scadenti, la qualit delle sue immagini sempre elevata.
Anche la mappatura delle Regioni Lunari fotografate buona.
In questo caso specifico, tuttavia, ci sembra giusto sottolineare che il rilievo chiaro che lui ha evidenziato e qualificato come "raggio di luce", a nostro parere potrebbe non essere affatto un raggio di luce in senso tecnico (e cio un certo quantitativo di luce solare - radente, dal punto di vista della Regione Lunare coinvolta - che filtra attraverso uno o pi cracks che si aprono sul bordo (rim) di un cratere e ne illuminano il fondo).

The Moon from Cassini-Huygens.jpgThe Moon from Cassini-Huygens - Lunar fly-by of Aug., 18, 1999123 visiteUna serie di tre fotogrammi montati in sequenza e relativi al passaggio ravvicinato ("fly-by") della Sonda Cassini-Huygens accanto alla Luna. Era il 18 Agosto 1999. Ed eccoVi la "original caption" relativa a questo evento, dal "NASA Picture of the Day" del 10 Settembre 1999: "...the Cassini spacecraft flew by the Earth and Moon, then continued on its way to the outer solar system. Near its closest approach to the Moon, a distance of about 377.000 Km, controllers tested Cassini's imaging systems on this most familiar celestial body. This composite picture shows three resulting lunar images from the green, blue, and ultraviolet regions of the spectrum (left to right). Prominant in the upper right of each image is the dark, round Mare Crisium (Sea of Crises) at the eastern edge of the Moon's near side. With its cameras clearly functioning well, Cassini's (...) expected to arrive at its final destination, the Saturnian system, in 2004".
La storia, come sapete, ha avuto un lieto finale.

The Moon from Galileo-gal_p37329.jpgThe Western Hemisphere of the Moon from Galileo121 visiteCaption NASA originale:"Galileo color image of the Moon showing the western hemisphere and Orientale Basin.
The Orientale Basin is just left of the center of the image, at 20° S, 265° E, and has a diameter of about 1000 Km. The right side of the image is on the Moon's near side and left on the far side. The dark area at upper right is Oceanus Procellarum while below it is the circular Mare Humorum. The dark region at lower left is the South-Pole-Aitken basin. The image was produced from three exposures, through violet, red, and near-IR filters, from roughly 560,000 km. (Galileo, P-37329)".
