## Catalogue data

### WHAT KIND OF THING IT IS

What the object is in itself, rather than how it happens to look from here.

| Field | Value |
| --- | --- |
| Spectral type | sdM1 |
| Luminosity (visual) | 0.00352209 L☉ |
| Variability | UV Ceti flare star |
| Variability type (GCVS) | UV |

### 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 |
| --- | --- |
| Colour index (B−V) | 1.524 |
| Variable magnitude, brightest | 11.86 |
| Variable magnitude, faintest | 12.09 |

### 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 |
| --- | --- |
| Proper motion (RA) | −1165.35 mas/yr |
| Proper motion (Dec) | −899.95 mas/yr |
| Radial velocity | −148 km/s |
