| Proposal | WX Her is a short period mira with a continuously decreasing period. It has been monitored by SAAF/V (Swedish Amateur Astronomers Association / Variable star section) since 2012. From our data and old data from DASCH it has showed a steady decreasing period over 100 years. From about 187 to 179 days, I wish to have the star observed once a week for one year to help keep monitoring its period. At least with V-filter but preferred with VRI or BVRI. |

The brightness is about 11.5-16.5 in V. In B it is about 13.5-18 and 11-14.5 in R. For I I have no observations.
