Could it be that I detected an error in CDS's SIMBAD Astronomical Database? Anything goes · Danny Caes · ... · 2 · 186 · 0

Here's a strange case. Is the supercluster of galaxies known as SCL 91 composed of two different superclusters? That's what SIMBAD shows. SCL 91: the VELA supercluster and the LEO-SEXTANS supercluster. The coordinates of the VELA supercluster (according to SIMBAD) are: R.A. 10:53 / Decl. +2°44' (too much northward, these are the same coordinates of the LEO-SEXTANS supercluster). Have I really detected an error or is SCL 91 indeed a composition of these two (totally different) superclusters? By the way, I also discovered a "trick" to get SIMBAD's huuuuuuuuuuge (!) alphabetic list (or overview) of all the officially named astronomical objects beyond the solar system and the most remote superstructures in the universe! Piece of cake.

There seems to be 300 superclusters in the SCL catalogue. What if there were only 299, or much more than 300, for example: 301. Strange thoughts…

Hi Danny. If you find an error in the CDS SIMBAD Astronomical Database, you can use an annotation and make a comment  or report an error about it. Go to:  https://cdsannotations.u-strasbg.fr/annotations/simbadObject/3443683/new , register your name, and then you can log into the CDS yourself and add your comment. I've made many of these before. Example here is *iot02 Nor. You can find access at the far bottom of the page of any object in SIMBAD. Read this first https://simbad.cds.unistra.fr/guide/annotations.htx
If you find an error be direct with your response, explaining why. Normally someone will look at it and correct it. If it's valid, your comment stays there, and can be viewed by anyone who may come up with a similar problem that has occurred in the past. Hope this helps!
