Last week was the 247th meeting of the American Astronomical Society (AAS), which was held this year in Phoenix, Arizona. NuSTAR appeared in 24 abstracts for the meeting, covering a broad range of topics. Among the highlights was a special session on Monday dedicated to the legacy of Dr. Katja Pottschmidt, who led the NuSTAR Guest Observer Facility (GOF) until her untimely passing last year. Katja studied the spectral and temporal studies of accreting black holes and neutron stars in our Galaxy and is sorely missed by the high-energy community. Other talks and posters highlighted NuSTAR contributions to studies of neutron stars, magnetars, fast X-ray transients, supernovae, and accreting supermassive black holes. Many of these contributions emphasized the time-domain, studying transients, orbital variations, and other forms of high-energy variability.
