Itagaki.   TCP J12355226+2755557 discovered 2024/01/04.7998 by K. Itagaki again.   TCP J12355225+2755557 discovered 2024/02/12.736 by K. Itagaki yet again.   TCP J12355230+2755558 discovered 2024/04/08.0306 We have a Photometry reference image made by Odd Trondal.   So, which name do I use? I picked the shortest one 2016blu, even though it will live in the supernova 2012 archive.   This supernova is in the Constellation Coma Berenices.
