The Goddard Space Flight Center's Solar EUV Rocket Telescope and Spectrograph (SERTS) was successfully flown on six different occasions, and results from several of those flights are presented here. For the flight of 1995 May 15, SERTS included a multilayer coated toroidal diffraction grating which enhanced the throughput above that of a standard gold coated grating for wavelengths between about 170 and 220 Angstroms, with a peak response around 192 Angstroms. Emission lines in this wavelength range are seen in second order. First order lines between about 235 and 335 Angstroms are also detected. A total of nearly 140 lines are identifiable in the combined first and second order wavebands. These include lines from several ionization stages of Ca, Mg, Ni, S, and Si, as well as lines from at least nine ionization stages of Fe (IX -- XVII). Many of the lines are useful for calibration verification, plasma diagnostics, or both. Results from analyses of the high spectral resolution (30 m Angstroms in second order, and 55 m Angstroms in first), spatially resolved (4.4 arcsec spatial resolution) active region spectra are presented. For the flight of 1993 August 17, SERTS included a multilayer coated grating which enhanced the instrumental sensitivity within the first order waveband. For this flight we also obtained coordinated Very Large Array (VLA) radio observations at 20 and 6 cm wavelengths. Because the radio emission is sensitive to the coronal magnetic field while the EUV emission is not, we were able to derive solar coronal magnetograms from the combined SERTS and VLA observations.
