Good Morning, 0bservers!
First, we got the standard NASA video loops and other data back. Not sure what they "lost" but Ben did prove that there are other source locations for data. Still, it should not have taken that long for NASA to do server maintenance. Anybody in IT would tell you that indicates either serious problems or serious incompetence.
Speaking of incompetence, my apologies for not posting yesterday. I had the report all prep'd and ready... and I completely forgot to submit it! I did that just a while ago so you'll be getting yesterday's news today. Sorry about that, everybody!
Now, the weather...
There was a rise in Particle Density most of yesterday, with a sharp rise around 2200 UTC before a sharp drop after midnight UTC. Normally, that would indicate a rapid increase in solar wind speed, but it didn't. Indeed, wind speeds dropped from an early morning high yesterday of 450 KPS to a low of around 340 KPS at midnight, followed by a relatively steady rise to 380-400 KPS as of 1000 UTC. We also had a pretty sharp drop in Temperature readings to 4100°K about three hours before the Particle Density rose, but it rebounded back above 5000°K by 0200. As to the Phi Angle, it had a sharp change just prior to the Particle Density increase, and the Bt/Bz polarities were clashing around that time as well. When the Phi Angle started to stabilize around midnight UTC, that's when the density dropped. However, the Bt/Bz polarities are still quite close with occasional collisions which may be why we're seeing another density increase right now.
So, with all of those indicators, you'd expect a sharp rise in wind speed and impacts on our magnetosphere. But yet, nada, zip, zilch. Why? Because this wasn't the result of a CME or increased coronal hole activity. Instead it was a sector boundary crossing. What's that, you ask? Go to this link for the discussion. By the bye, I didn't know this before so I'm no "genius" in solar dynamics. But I am learning, which is more than half the fun!
KP-Index readings only rose slightly yesterday from KP-1 to KP-2 around the time of the Particle Density increase. NASA is predicting a KP-4 (minor geomagnetic storm) sometime in the next 24-48 hours, but that's not really much of a concern. Magnetometer readings are nominal, as are the Proton Flux and Electron Flux charts. Continued calm on the X-Ray Flux chart, with a slight rise in background radiation just before midnight UTC followed by a continued downward trend toward the middle of the Class A range. The large Southern coronal hole system is passing the midpoint now, we may see some increased wind speeds from that in the next 24-72 hours. And we've got a new sunspot group in the Northeast, but so far it isn't overly active despite a Beta-Delta level of magnetic complexity. The LASCO-C3 did show an ejection in the Southwest starting around 0200 UTC, but it appears to be a slow/steady one and none of the ENLIL spiral loops have picked up on it yet, so it may not be Earth-facing.
