Thanx @DaveC426913 When Jozsef came up with erratic results I kinda figured that my result of 173.01 Km was a fluke. Hopefully, in the next Steve event we will get a location where Steve is directly overhead and then I will use the same code I used for my GJ event a few months ago. There is...

So, is the result I got of 173.01 Km a reasonable calculation?

@DaveC426913 Could this be why Jozsef was getting erratic results when factoring in the azimuth and elevation? Is there another formula that we can use in this case? Jun Wang was located directly north of Calgary and Alan was located southeast of calgary. They were about 120 Km apart.

Yes... @DaveC426913 but I was asked not to post it because They were taken near their homes. I decided to just post the distance between them which was 120 Km. Jozsef and I decided that the best way to approach this is to find an image that is directly below Steve and that one of the stars...

@Bill Archer @DaveC426913 I recently found a pair of images that could have been taken just seconds apart. I decided to find the highest altitude star, within the ribbon of Steve, for each photo and use that in the formula that @DaveC426913 used in his calculation. I first found the highest...

@DaveC426913 @Bill Archer I just got some feedback from Jozsef Bor and he examined the photos we were using for the calculations and indicated, like what @DaveC426913 indicated also, that there are no common elements. I guess we will just have to wait for the next STEVE event and hope that we...

@Bill Archer I just got a facebook message from Andy Witteman of the AAC and here is the quote: "In Fairbanks, we're a bit too far north to see him out (we've had 2 this year) but back in BC last year it was like a once a week thing. you would almost be best off setting up 3 or 4 webcams in...

@Bill Archer Sounds interesting. My other approach to this is to find a longitude and latitude where steve can be seen looking straight up at about 90 deg and then use that location as a reference or a constant in the code. I will still need the location of other photographers, with the same...

@Siv Heang Tav I am now a member of the AAC so send it to me via personal message.

@DaveC426913 It's just when I upload them to get the astrometry that it fails to get the results but yes, I can view them in this thread. I don't know why the links are broken. Could be congestion at the server. I'll run the program again tomorrow and see what happens.

@Bill Archer @DaveC426913 I have a friend from Hungary named Jozsef Bor (http://www.ggki.hu/en/staff/researchers/bor-jozsef-mta-ggki/) that is in the process of trying to find a code that will take into account both photographers location and the curvature of the Earth and he will try to help...

@Siv Heang Tav It failed again. Was the lens set to 14mm or 24mm?

@Siv Heang Tav Both photos failed.I upload Paul's image to test the server and his works fine. Do you watermark your photos?

@Siv Heang Tav Can you post a photo of the night sky, or an aurora, that was taken by your Nikon 14-24 F2.8. I want to see if I can get the astrometry from it before you use it to capture STEVE. Thanks.

@Siv Heang Tav Not necessary, the top of the arc of STEVE is what we want and in the center if possible. I will take care of finding a reference star. @DaveC426913 That would help but only the hardcore citizen scientists will do that, but then again you never know. I have a Christmas party to...
