[meteorite-list] coloma witnesses
Hi Folks, I'm going back to Coloma on Friday and staying for another week. While I am there I would like to interview some witnesses in Coloma and surrounding areas. Very few witnesses from near/inside the strewnfield submitted reports to the AMS and it would be good to get these reports. When I do the interview, I usually use a tripod, inclinometer and GPS compass. This allows me to capture the azimuth and elevation angles for the beginning and ending points as accurately as possible. Any data I gather I will submit to the AMS site and it will be publicly available. I want to do these interviews in an attempt to improve the information we have on the trajectory. If you have any good witness reports from people you met in the field, who actually saw the fireball or smoke trail please consider passing on the witnesses contact info to me off list. A name and email or phone number for each witness would be great.

Re: [meteorite-list] coloma witnesses
Dan, Thanks yes I did see the video. Very awesome. I've been able to do some work utilizing the topographic features of google earth and mapping them to the pictures, but there's still a good bit of uncertainty. With regard to the picture and video, what we really need to do is get out to these 2 locations (North Reno for Lisa South of Fresno for the video) with a DSLR camera, tripod and a clear night. Then take an astrophoto recreating the same field of view as was used in the fireball images, but also capturing stars in the image. We could then stretch out the 2 sets of photos in photoshop so that the mountain and ground features line up. At that point we would have very nice AZ EL readings for both of these photos. I'm working with someone now who is trying to get these calibration photos done, but he has limited time and it might take him a month or more to get it done. So.. if anyone is near reno or fresno and would like to help out with this effort please LMK. Based on the witness reports I've reviewed so far, I believe there is a bit of northern tilt to the trajectory. My hope is that by interviewing witnesses close to coloma, we maybe able to confirm this. Any witness contacts will be put to good use, so please send them to me, if you got em.

Re: [meteorite-list] coloma witnesses
Dan, I can't say with much certainty right now. The trajectory Jake came up with is the best guess right now and I do think it is very close to reality. However, based on some witness reports and also analysis of the 2 videos I think there could be a 5-10ยบ tilt toward the north as opposed to a straight E-W track. Take this with a grain of salt though because I can not prove this right now.
