Good Morning, 0bservers!

    
     
Solar wind speeds got a little weird around midday yesterday, topping out at 525 KPS only to drop to 410 KPS less than an hour later and jumping back to 500 KPS. It's had a steady and slow drop since then, dipping below 450 KPS around 1000 UTC. Particle density jumped around the time the wind speed dipped, but this seems to have been tied to a Bt/Bz polarity collision (which scrambled the Phi Angle for a while). That collision caused a brief spike in Temperature to almost 5700°K, then returned to a 5100°K-4700°K until midnight, and then it dropped precipitously after midnight and is currently in the 4100°K-4300°K range. Oh, and we had more collisions after 0500 UTC, again making the Phi Angle go both doo and lally. The Magnetometer surprised me a bit, with an earlier than expected high/low sine wave, topping out at 140 nT, but the lower end was 65 nT, well above the 40 nT threshold. The KP-Index remains green, with mostly KP-2 readings and a few KP-1s. The Proton Flux remained nominal, and the Electron Flux was mostly nominal, but the readings for the latter did rise up close to the alert threshold but went back down. The X-Ray Flux was surprisingly dull, with pretty much zero spikes as well as a slight downward trend continuing in background radiation. The ENLIL Spiral is showing some sort of ejection heading this way from yesterday, but I couldn't find anything corresponding to this on any of the video loops (including the LASCO C3). Ben confirmed no ejection in the video above, so we're good...
