Can someone tell me what is going on with the Solar Wind Density? [

I have never seen this chart look like this. I will save a screenprint, in case it changes. This table usually looks solid green. I am seeing a red triangle??
Here is a screenshot of it, in case the charts change.

It looks like the triangle on the Solar Wind - Density chart is in direct inverse to the drop on the Solar Wind - Speed chart. Does this mean the solar wind got extremely dense, but had no speed? I am also looking for a legend on the chart color. I haven't seen red on this chart before; it is usually green.
when i click on the "more data" button below the density chart that they have, it directs me to the ACE data charts

i see there could possibly be a spike around just before the 16:00UTC mark
so lets go look directly at the ACE density data for today
it looks like there is a gap in data right around that same time
[

that gap is seen on all the ACE charts

but when you look at this chart
[

we can see that the data gap occured directly after a large spike in Density and sharp drop in Radial Speed
one more chart for this

so lets look at the direct ACE density numbers for around that time. Here is the full day list for today

scroll to the 15:28UTC mark in the left collumn
there we can see a spike in Density begin @ 15:28UTC
Solar Wind Speed: 265.1
Density: 48.7
this is a Drop in sloar wind speed from 281.7, that it was 1 min before, down to 265.1
with an increase in Density from 2.3 that it was 1 min before, up to 48.7
then 1min later @ 15:29, we see the very large spike
Solar Wind Speed: 241.4
Density: 109.3 (!!! WOW !!!)
this makes within 2min time, a solar wind drop of around 40km/sec and a increase in proton density of around 107!
then we had the data loss, the gap we seen
and when it came back online, all is back to where it was prior to the spike
