Cal 87 was observed with with XMM-Newton in April of 2003. The source shows a rich emission spectrum, where lines can be identified if they are red-shifted by 700-1200 km s –1. These lines seem to have been emitted in a wind from the system. The eclipse is observed to be shifted in phase by 0.03 ϕorb, where ϕorb is the phase of the optical light curve.
