## 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 | G5III |
| Luminosity | 133.906 L☉ |
| Variability | RS Canum Venaticorum active binary |
| Variability type (GCVS) | RS |

| Colour index (B−V) | 0.843 |
| Variable magnitude, brightest | 8.57 |
| Variable magnitude, faintest | 8.65 |

### 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) | 6.67 mas/yr |
| Proper motion (Dec) | 14.37 mas/yr |
