Suspected discovery

posted on: 15 June
15 June, while compiling an observing guide for the reflection nebula Lynds 578 (a.k.a. Van den Bergh 1 and Rojkovskij-Kurchakov 2) in Cepheus I noticed a (reflection) nebula to the west-southwest involving the mag. 7.9 B9 star SAO21137 that, to the best of my knowledge, is uncataloged.
