Equatorial Maba Beach: From Big Dipper to Southern Cross \u2013 annotated<\/p><\/div>\n

While staying at Maba village<\/a> on equatorial Indonesian island Halmahera<\/a> in this March, I realized one amazing fact. This place with latitude only 40’N, is the best one to capture both of commonly known “pointer” showing the celestial poles<\/a>. As the north celestial pole can be found by stars of the Big Dipper<\/a> (pointing to the star Polaris<\/a>), the south pole is possible to find by the Southern cross<\/a>. Check this on annotated image version<\/a>. Both of these celestial “shapes” were perfectly visible in the late night of 4th March 2016 from incredibly dark place of the Maba beach, where I was taken by such a nice local citizen Mr. Hardi, followed by his uncle Mr. Haruna. Both of them came on the beach and sat on a log of dry wood, nearby a fading campfire. Apart from both celestial shapes, the sky was enriched by rising center of the Milky Way<\/a> (“Miett” in local Maba language) with bright “red” planet Mars<\/a> and a bit fainter Saturn<\/a> close to the bright red star Antares<\/a> in the Scorpius. Strong lights on the right come from the village, partly disturbing view to the southern Milky Way with pink Carina nebula<\/a>. On the left, the light belongs to far nickel mining company. But not only artificial lights<\/a> were captured. Red and green “flames” in the sky are caused by natural atmospheric airglow<\/a>. Beautiful Mobon Island behind the guys completes this calm but memorable view as a foreground in the Jiko Mobon Gulf (Gulf around Mobon Island). This image was taken during expedition for dramatic total solar eclipse<\/a>, which occurred a five days later. Used Canon 6D IR Baader modified, Samyang 24 mm, f2.8, ISO 10000, 24×15 seconds panorama from tripod.<\/p>\n

I would like to acknowledge support for the eclipse expedition to Indonesia which was provided by NSF grants<\/a> AGS-1144913 and AGS-1255894, NASA grant NNX13AG11G to PI Shadia R. Habbal<\/a> of the Institute for Astronomy, the University of Hawaii<\/a>, and the use of the local government building in Maba, with help from Xavier Jubier<\/a>, without whom this image would not have been made possible. <\/p>\n","protected":false},"excerpt":{"rendered":"
