"Earthshine blog"

A blog about a telescopic system at the Mauna Loa Observatory on Hawaii to determine terrestrial albedo by earthshine observations. Feasible thanks to sheer determination.

Scripts running

Observing log Posted on Jan 21, 2014 12:40PM

It was possible to start a simple observing script today: Mount was not attached so nothing moved except shutters and FWs (and the SKE is still not working) – files were obtained but it turned out that something with the setup of permissions on the PXI has changed so images could not be written to the ‘NAS’ drive (a network drive in the instrument rack). Am seeking help from DMI IT department for this.

If that starts working we can run tests on bias fields at least, and later on flat fields (with a screen of some sort in the distance) and then focus tests and all this.

Henriette sent us this:

Jens Hoijemakers in Leiden wrote a thesis about a telescope you could put on the Moon and monitor Earth with – an earthlight telescope!

He has a YouTube video: http://www.youtube.com/watch?v=AcofvAjVT7Y

His thesis is here:

And here is a paper.

Thanks Henriette!
