Subject: Sgr A* Campaign

Dear Members of IAU Division J, Galaxies & Cosmology:

Dr. Steven Willner (CfA) asked to circulate the invitation below.

Sgr A* monitoring in 2017 July

After our successful campaigns in 2016, the Spitzer Space Telescope and Chandra X-ray Observatory have allocated time in 2017 July for simultaneous monitoring of Sgr A*, the variable source at the center of the Milky Way galaxy.  The plan is to have two campaigns lasting 24 hours each.

We invite others interested in monitoring Sgr A* to consider scheduling observations during the Spitzer/Chandra monitoring in order to enhance the value of all data sets.  Further details are at https://www.cfa.harvard.edu/irac/gc/.

 

Sincerely,

Claus Leitherer

(for the Steering Committee of Division J)
