## Catalogue data

### HOW BRIGHT IT IS

What the light adds up to, measured through one filter at a time. A magnitude is a brightness on a backwards scale — the smaller the number, the brighter the object.

| Field | Value |
| --- | --- |
| Apparent magnitude (B) | 12.51 |
| Apparent magnitude (V) | 12.47 |

### WHERE IT IS AND HOW IT MOVES

Position, motion across the sky and the size it covers on it. These are measurements of the object as seen from here, so every one of them depends on where here is.

| Field | Value |
| --- | --- |
| Major axis | 1.8′ |
| Minor axis | 1.6′ |
| Position angle | 0° |

### WHEN IT WAS FOUND

Who first saw it, from where, and by what method.
