I saw this bowl a few weeks ago but could not find it in the pattern catalog downloader. I searched through May Blog until I found and downloaded it. The PDF calls it Concentric Rings Basket. I don't think it is in the current catalog.
I have a suggestion which I am sure you thought of before. I try to use naming conventions to specify the item category first and then the name of the particular variety or subset of that item, e.g. instead of "Concentric Ring Basket" I would use "Basket Concentric Ring". That would make it easier to search the catalog without looking at all the thumbnails. Just a thought from someone who admires and appreciates your work and passion for scrolling.
