I agree that this definitely looks like a previously obscured observation which would have made the observation have a positional accuracy in the range of 25-30 km. I wanted to see if this affected other observations of the species in Canada (where it looks like obscuration was lifted), so I flipped through the Identify modal to get a quick view of this.
When I look in Identify, however, the correct accuracy of 43m displays?:
If I click on “View” and look at the observation page, it returns the 26.55 value. Not sure what is going on there.
