    "abstract": "We present experimental results for pattern formation in Rayleigh-Benard\nconvection of a fluid with a Prandtl number, Pr~ 4. We find that the\nspiral-defect-chaos (SDC) attractor which exists for Pr~1 has become unstable.\nGradually increasing the temperature difference from below to well above its\ncritical value no longer leads to SDC. A sudden jump of temperature difference\nfrom below to above onset causes convection to grow from thermal fluctuations\nand does yield SDC. However, the SDC is a transient; it coarsens and forms a\nsingle cell-filling spiral which then drifts toward the cell wall and\ndisappears.",
