Rapid Variability and Annual Cycles in the Characteristic Timescale of the Scintillating Source PKS 1257-326
Rapid radio intraday variability (IDV) has been discovered in the southern quasar PKS 1257326. Fluxdensity changes of up to 40% in as little as 45 minutes have been observed in this source, making it, along with PKS 0405385 and J1819+3845, one of the three most rapid IDV sources known. We have monit...
