We present a global model of plasmaspheric hiss, using data from eight satellites, extending the coverage and improving the statistics of existing models. We use geomagnetic activity dependent templates to separate plasmaspheric hiss from chorus. In the region 22–14 magnetic local time (MLT) the boundary between plasmaspheric hiss and chorus moves to lower L∗ values with increasing geomagnetic activity. The average wave intensity of plasmaspheric hiss is largest on the dayside and increases with increasing geomagnetic activity from midnight through dawn to dusk. Plasmaspheric hiss is most intense and spatially extended in the 200 to 500 Hz frequency band during active conditions, 400 < AE < 750 nT, with an average intensity of 1,128 pT2 in the region 05–17 MLT from 1.5 < L∗ < 3.5. In the prenoon sector, waves in the 100 to 200 Hz frequency band peak near the magnetic equator and decrease in intensity with increasing magnetic latitude, inconsistent with a source from chorus outside the plasmapause, but more consistent with local amplification bysubstorm-injected electrons. At higher frequencies the average wave intensities in this sector exhibit two peaks, one near the magnetic equator and one at high latitudes, 45∘ < |Λm| < 40∘, consistent with a source from chorus outside the plasmapause. In the premidnight sector, the intensity of plasmaspheric hiss in the frequency range 50 < f < 1,000 Hzdecreases with increasing geomagnetic activity. The source of this weak premidnight plasmaspheric hiss is likely to be chorus at larger L∗ in the postnoon sector that enters that plasmasphere in the postnoon sector and subsequently propagates eastward in MLT.
JOCKEY QUOTES GARY STEVENS, AVANZARE, WINNER: “He had tunnel vision in the starting gate. I was able to go out there and Fernando (Perez, on El Nino Terrible) set a decent pace that was comfortable. He kicked home really nice and he was giving me that feeling down the backside.“I breezed him five days ago on the dirt and when I looked at the work, he had the second-fastest work that morning (at the distance.) I thought he went in 1:01 and he actually went in 59 and usually when they do that they’re doing awfully well. He’s a great turf horse and he’s still improving. He’s gained some confidence from the Native Diver, which was the first time I rode him. It was kind of gooey and he didn’t seem like he was enjoying it but he still ran third.”TRAINER QUOTES WINNING TRAINER TOM PROCTOR HAD NO COMMENT NOTES: The winning owners are Donato Lanni or John S.
