September Auroras Round 1
Well, nothing super but it was nice to get out again since there wasn't work today (I wish)... earlier in the evening the activity index was super high but by the time it got dark things had started laying back down.
I wanted to try out a new spot I'd seen walking the dogs so here's a couple pictures from a thermokarst pond back on the ski trails near Jurassic Peat. I walked the perimeter as best I could in the dark (reminded me of wandering through totem park without a light back when I was a kid). I had a light and turned it on a couple times to so I wouldn't fall into the pond but otherwise was crunching around in the dark. A bird and I mutually scared ourselves to death but otherwise it was pretty uneventful.
Here's one from me goofing around. Kind of different sort of picture with all that steam that you can't see when the flash isn't used. So, hopefully I'll get some more interesting stuff from this place as the fall goes on. Cousin Bill^jr. is coming up in a couple weeks so hopefully we can treat him right, too. Well, until later...

Hello there Bob. Can you please explain to me the following:
1. What makes auroras?
2. Why are they only around sometimes?
3. Why are they green?
4. I think that's it for now. thanks, anne mcshane

Hi Anne,
Hopefully Kim will drop by because he knows way more about the aurora than I but here's another helpful link:
Wikipedia's Info
The solar wind is kind of hitting the outer parts of the earth's atmosphere and the different colors (red, green, etc.) are the different elements (like oxygen) being excited. When the elements get excited enough we see the colors. I guess the aurora's going all the time it's just more active sometimes so we can see it.
Here's a super cool picture I saw at the wikipedia site:
South pole view from space
I just came across this site this week that the IARC director sort of maintains:
Dr. Akasofu's Home Page
The coolest link I found there is to this site:
Solar Activity Comparison Plots
The cool thing there is comparing the real to the predicted and also seeing what's predicted into the future. So, I just have started looking at that lately.

Yeah that would be rad! I was just reading an article someplace about how there aren't as many fireflys as there used to be. That's kind of a bummer. I remember they stank but they were still pretty cool to catch and stuff growing up.
