Radio Pulses along the Galactic Plane

We have surveyed 68 deg^2 along the Galactic Plane for single, dispersedradio pulses. Each of 3027 independent pointings was observed for 68 s usingthe Arecibo telescope at 430 MHz. Spectra were collected at intervals of 0.5 msand examined for pulses with duration 0.5 to 8 ms. Such single pulse analysisis the most sensitive method of detecting highly scattered or highly dispersedsignals from pulsars with large pulse-to-pulse intensity variations. A total of36 individual pulses from five previously known pulsars were detected, alongwith a single pulse not associated with a previously known source. Follow-upobservations discovered a pulsar, PSR J1918+08, from which the pulseoriginated. This pulsar has period 2.130 s and dispersion measure 30 pc cm^-3,and has been seen to emit single pulses with strength up to 8 times theaverage.Comment: 14 pages, 5 figures, AASTeX, accepted by the Astrophysical Journa
