Looks like fireblight to me.
I had issues almost from the moment blooms appeared last year.
Looks pretty typical for FB in the earliest stage but here’s a link to help identify it http://msue.anr.msu.edu/news/scouting_for_blossom_blight_symptoms_of_fire_blight_in_apples

Looka like fireblight to me. Every time I’ve waited to prune out what might be fireblight, it has been fireblight. My rule now is prune it out everything that might be fireblight before it gets worse. Maybe I’d think differently if I had very mature trees.
Looks like Blossum Blast to me. My ‘20th Century’ pear gets it some years more than others. The tree is also prone to rogue blooms, which may be connected or simply coincidence. I’m leaning toward the former being the case.

Mr. Clint,
I had it on my 20th Century, too, about 4 years ago. The description you posted “Unlike fire blight, infections seldom progress past the base of spurs and are usually concentrated in the lower portion of the tree’s canopy” fits the bill.
It affected the lowest branch of the tree, all the blossoms on that branch wilted, dried out but nothing beyond that. Not a single fruit on this branch that year. The rest of the tree produced normally with no issue.
There have been some flowers and fruit on that branches after that year.

It’s probably a form of Blossom Blast too. I hope you’re not lopping off branches because of this.

I pruned out one branch earlier. I’ll monitor this one. Thanks!
