A new blog for the upcoming total solar eclipse

Monday, March 6, 2017

Greetings from the High Altitude Observatory! In anticipation of the rapidly approaching August eclipse, we would like to let everyone know what we are doing in preparation. Toward this end, we welcome you to our new eclipse blog.

We have some exciting observational projects lined up this summer in anticipation of the Total Solar Eclipse occurring over the continental United States on August 21 (https://www2.hao.ucar.edu/solar-eclipses). It's our intention to periodically update this blog with progress (and setbacks) in order to provide a glimpse into the work of our engineers and scientists. 

First of all we are developing a Fourier transform infrared spectrometer (FTIR) Fourier transform infrared spectrometer (FTIR) instrument (pictured at right) to obtain a survey spectrum of potentially interesting solar emission lines in the infrared portion of the spectrum between about 1,000 and 10,000 wave numbers (cm-1).  Our hope is to identify selected lines which may be of use to study coronal magnetic fields.   

A second project will be a technology demonstration of a novel camera technology for studying linear polarization within the solar corona.   

Stay tuned for updates on these two exciting projects!

This image shows both the plumes at the solar poles and the coronal streamers nearer the Sun's equator at onset of Solar Cycle 23.)
