Beige behind-the-ear hearing aid in pouch

I lost my beige behind-the-ear hearing aid last night around 3:15 PM. It was tucked in a small navy zip pouch inside my coat pocket, and I think I had it near the Memorial Union on the Iowa State University campus in Ames. The device is a beige BTE model with a tiny dent along the top edge and a green silicone dome on the right ear tip. If you look closely there’s a bright red wax guard visible at the speaker. I rely on this daily and it’s expensive to replace, so I’d be really grateful to get it back.
