For once clear Skies for an astronomical event, and too far South.

I hate to say this Mike, but in Durham (about 15 miles away from you?) 
we've had two fantastic nights of aurora - Wednesday night from 7pm to 
8pm had aurora over the whole Northern half of the sky, while last 
night, despite the forecasts, the cloud suddenly cleared at 10pm to give 
an utterly amazing display for over an hour, and all in the Southern 
half of the sky!  Many photos taken, but on the downside my Z-1 fatally 
malfunctioned while shooting.  I'll get the films developed tomorrow.  
As you say, tonight has been relatively clear, but no signs of a repeat

Question for all you out there who do any sort of sky/night time photography.
Is there any rule of thumb for shooting Auroras.
Open the shutter and count to 10 - 20? 30? Set the camera on auto and let 
it sit and expose for a few minutes?
I suspect it's all just trial and error but I'd still like some hints.

You have an LX if I remember correctly.
Put it on a tripod, set the camera on auto with a stop of
overexposure compensation (use print film) and open the shutter.
The LX is good at this stuff.

Re: Shooting Auroras

[Jostein]

correct exposure time for auroras varies a lot with the intensity of the
light.
William Robb suggested 1+ compensation and print film.
Print film is probably a good idea because of its wider latitude.
In my limited experience, setting exposure compensation to -2 worked fine,
but that was there and then, I guess.
Also, the length of the exposures varied _much_ with the intensity of the
auroras.

I have some of the images on my web.

Best,

Re: Shooting Auroras

f1.4 is just a good starting point. f4 with 400ASA would come
out to a 1/2 second exposure with my table. Did you shoot
the LX on AP? How long do you think the exposure was?
 I bet the LX nailed it though. Let us know what you get back.

 Steve,
 Thanks for the guide
 and to Peter for the other link

 http://www.ptialaska.net/~hutch/aurora.html

 I've noticed that you both use wide open. Is this to get the shutter speed
up?

 For eclipse stuff, the guides are usually calculated around f8 (but that
 could just be because it's as wide open as you're going to get with an
 extreme long lens!)

 I used my LX and M20mm the other night but that has only a max aperture of
 f4. Grabbed some Royal Gold 400 and shot a few frames. I'll drop the roll
 off on Tuesday - won't get my hopes up that I've caught anything
worthwhile!

 That's what I thought.(didn't think of compensation though)
Then my nerve
 failed when the shutter seemed to have been open for an
eternity. I
 switched it  to B and counted to 10, then 20, then 30.
 It wasn't a particularly impressive display anyway, mostly
white with a
 hint of green. If I get to see the lights again then I'll be a
bit better
 prepared (hopefully)

Auroras and the like are actually pretty dim, so you want to
have a fast lens, wide open. My best Hale-Bopp stuff was with
the LX on auto and the 50mm f/1.2 wide open. With the comet, I
set the exposure comp to minus 2 stops because of the scene
type. With northern lights, I would give a plus exposure comp
for the same reason.
We had the same light show here in Regina. Foolishly, I missed
it. Imagine throwing cupric chloride into a camp fire..
I guess it was quite the show farther west, and somewhat north.

Trial and error works. :^)

I had been making exposures ranging from 5 - 20 seconds with 400 
speed film and F2.8 lenses and not getting enough light. Lately I've 
been doing 30s. The film is still in the freezer so I don't know how

well, there is a way to be sure on the spot, if you have a capable enough
digital camera. set the ISO the same, set aperture priority and see what
happens, if your camera can expose that long. then use your film,
accounting for any reciprocity failure. i'm limited to 8 seconds so i can't
do these types of exposures, but i shoot fireworks that way. as someone
else pointed out, the LX would do it right without help.

Re: Chance of auroras tonight.

We have 100% cloud cover here in America's Outback (southern

I guess aurora viewing will be out of the question for this
locale.  Thanks for the heads up, though.

 AURORA WARNING: Twisted magnetic fields near giant sunspot 69
erupted on
 Friday, Aug. 16th. The explosion sparked an M5-class solar
flare and
 hurled a coronal mass ejection toward Earth. NOAA forecasters
estimate a
 25-30% chance of severe geomagnetic storms when the cloud
 arrives--probably on Sunday, Aug. 18th. Sky watchers should be

Well, if I was down south, where it is dark, I would recommend this:

Fast, Wide, Elite Chrome 200, maybe pushed to 400.

i.e., 28mm f/2, or 24mm f/2, or 24mm f/1.4

Vary the exposure from 10 to 60 seconds, in steps of 10 seconds

And REMOVE ANY FILTERS!

Obviously tripod and cable release...

You might try a fisheye wide open (f/2.8 ?) also.

Untill darkness comes back up here, I can only envy you ...

Beware of Auroras tonight (17-18. aug)

[Jostein Øksne]

Hi all PDML'ers in Northern America.
Just got in after two and a half hours of great aurora display.
At peak intensity it stretched across more than half the sky. It was
right above at some times.

If you have interest in such things and clear skies tonight, take a
look.
It may be worth it.

Auroras

[David A. Mann]

From http://www.spaceweather.com/

GROWING FLARE THREAT: Active region 9393 (aka 9433) continues to grow and 
now covers an area equivalent to more than six planet Earths. The big spot has a 
twisted beta-gamma-delta magnetic field that likely harbors energy for X-class solar 
flares. Three weeks ago sunspot 9393 unleashed the most powerful solar flare ever 
recorded. That's unlikely to happen a second time, but the active region nevertheless 
bears watching.

 According to their diagram it's currently pointing right towards Earth.  Another good 
flare-up would be quite spectacular :)

Cheers,


- Dave
