Some images from the solar eclipse earlier this month. We were south of Palu in Sulawesi, Indonesia.

A few partial phase shots and one of totality showing the impressive prominence visible that day.

The geeky shot - A flash spectrum of the Chromosphere.
When the Moon blocks all but a thin sliver of the Sun's surface, the light can be broken up into a spectrum to reveal the predominant chemical elements by the colour of light they emit. On the right is red Hydrogen-Alpha and the yellow line is due to Helium which was discovered in this way.
The other lines are H-Beta (light blue), H-gamma (dark blue) and Magnesium (green)
