  1. lol... the sky is currently still brighter than any northern lights you are ever going to see. Have some patience and try again in about 25 minutes.
  2. The Bz was strongly negative for about 45 minutes but has flipped. The density has come down to 7'ish from over 40, and Btotal is half of what it was, so G4-G5 levels aren't going to happen. When you factor in the transit delay, that favorable period should be arriving in about 30 minutes and will last for about 45. It should be plenty sufficient for a burst to G3. But we'll be fighting lingering daylight.
  3. Already a total Bz reversal. Might flip back, might not.
  4. Sweet jesus, this is absolutely ideal and suitable for as much as G5 levels of storming. Too bad it doesn't get dark until 10pm... conditions usually don't stay quite this good for more than a few hours. Solar Wind: 700.2 Density: 26.3 Btotal: 38.2 nT Bz: 37 nT south
  5. Nice brief G2 geomagnetic storm earlier today (well, yesterday). Conditions aren't favorable now but I checked a few times anyways.
  6. Last night was a good example of what a G1 geomagnetic storm will look like on a moonless night in NNE. Faint, but visible if you're looking. They're never really reported or acknowledged because they're common, occurring on roughly 900 days each solar cycle. Last night was somewhat noteworthy for a G1 in that the activity was weirdly high in the sky, meaning it was closer than normal. Also, as you noted the pulsing effect is a bit unexpected at such low activity levels. When I saw it, a small patch of sky would gradually get brighter over about 15 seconds and then abruptly fade out over about 2 seconds.
  7. Was this with the D5000? I'm super jealous of how clean and crisp it is. Really makes my camera (Nikon 8700) look pretty sad.
  8. I saw the animation of the CME and wrote it off.... it didn't look too impressive... certainly didn't expect a G4 storm from it. Figured it would be a nice show for Alaska.
  9. Pretty impressive how skillfully it managed to start fizzling as soon as the sun set. Best photo I could manage from tonight with frozen hands and 300mph wind.
  10. Wow, that's really great. I've kinda fallen out of photography so I'm not too up to date with the extent of the improvements. Being able to take shorter exposures would really come in handy tonight. My hands are like ice and I have to hold the shutter down because I don't have a cable release thingy.
  11. It'll matter in about an hour. The satellite that measures the data is way out there.
  12. Clearing out a bit. Very noticeable glow out there now and it's much higher in the sky-- promising.
  13. What you can get away with for ISO settings totally depends on your camera. If you've got noise, it's set too high. My camera is over a decade old and has horrible noise above ISO 200. New cameras supposedly maintain decent quality and go up to 1600 or even 3200. Secret tip: Leave your camera outside. Excessive grain/noise issues can be caused by heat on your cameras sensor, so keeping it cold makes a big difference. You can really see this in action if you look at dendrites webcam in the winter vs summer.

  15. I picked this up as a hobby from 2001-2003... you could see the lights about 1-2 times per month... the sun was just completely unhinged those years. Not much money to be made from small, grainy images. Would be nice though!
  16. I cry every time I think about losing the larger originals of these.
  17. Reds and violets are visible from the darkest locations in the strongest storms. Cameras will pick reds up easily, but the human eye won't. Most photos are long exposed and exaggerated in that sense, but the one you posted is probably very close to accurate. I've only seen reds and violets twice.
  18. Like you said, we're waiting for a substorm. Even with the 6 hours of Kp 9 in 2003, the actual show lasted maybe an hour before reverting to the bland green arc along the horizon.
  19. Bz is measured a million miles out in space at the L1 point, and Kp is derived from how disturbed a global network of ground level magnetometers are. A lower Bz will allow a greater disruption of the earths magnetic field and the Kp will rise as a result.
  20. Still, it's good enough to go back to a Kp of 8 apparently.
  21. Things holding steady in meh territory. Took a photo of the west through a hole in the clouds, about 45 degrees above the horizon, and it's violet. There is likely a greenish arc lower on the northern horizon hidden behind the squalls. Damn squalls are 10 miles away and I'm getting wind blown snow from them.
  22. It's basically the aurora light switch. If the value is north (positive) nobody sees anything except santa.
