We present the three-dimensional (3D) configuration of a filament observed by STEREO and the Global High Resolution H-alpha network in EUV 304 ? and Hα, respectively. This filament was the largest one located above active region NOAA 10956 that produced a small B9.6 flare and two Coronal Mass Ejections (CMEs) on 2007 May 19. The 3D coordinates of multiple tracing points on this filament were reconstructed by triangulation from two different aspect angles. In EUV observations, the two STEREO A and B spacecraft were observing the Sun with a separation angle of α 8.6 degree. While a similar angle was produced using the solar rotation of several hours for the ground-based Hα observations. The heights of the filament were calculated in both EUV 304 and Hα. We compare the results in both wavelengths and with previous measurements, and then discuss the similarities and disagreements.
