Reports Report 2017x (Event 2017-2013)

This report has been linked to the following event: Event 2017-2013
Observer
NameIan M
Experience Level3/5
RemarksI was on the phone with my mother who lives in Electra, TX, and she was on her back porch. We both witnessed the event, and after discussing our approximate observation angles we determined that it must have been the same one. We live about 2.5 hrs away from each other. Before realizing she saw it too, I initially thought the meteor's size was that it was less than a few miles away due to how fast it fell and how long it lasted. Afterwards, it realized that the meteor had to be larger, further away, and higher in elevation that I first judged.
