We calculated physical and orbital properties for 2M06464003+0109157, a 1.06day eclipsing double lined spectroscopic binary. We modelled the system'sASAS-SN and TESS light curves, measuring the system's inclination and radii ofeach component. Extracting radial velocities for each component from 6SDSS/APOGEE spectra, we measured the system's mass ratio and performed a fullorbital fit. Our analysis indicates that 2M06464003+0109157 has components withnearly equal masses ($m_1/m_2 =0.99 \pm 0.01$; $M_1{_,}{_2} = 0.57 \pm 0.015$M$_\odot$) and comparable radii ($R_1 = 0.66 \pm 0.05$ R$_\odot$, $R_2 = 0.57\pm 0.06$ R$_\odot$). The solution required two star spots to incorporate theout of eclipse variation that is seen in the light curve. We report our fullcharacterization of this system, and prospects for similar analyses usingsurvey data to measure precise physical and orbital properties for EBs.
