Abstract
The Space Star Anomaly in proton-deuteron breakup cross-section occurs at energies of about 10 MeV. Data for higher energies are sparse. Therefore, a systematic scan over star configurations in the range of intermediate energies between 50 and 100 MeV/nucleon is carried out on the basis of data collected with the large acceptance BINA detector. The preliminary cross section results for forward star configurations at 80 MeV/nucleon slightly surpass the theoretical calculations, but the systematic uncertainties are still under study. Also, a new variable describing rotation of star configurations is proposed.

Report
The report gives a status update of the study of the Space Star Anomaly in pd breakup based on analysis of data from BINA at 50-100MeV/A The introduction gives a readable background to the problem, followed by sections on the experimental work. Some representative results are given, with a forward look to future plans. The work should be published in the proceedings of the conference, as a well-written representation of the presented work at the EFB24 conference
