The active region AR9561 was observed during the survey on August 2, 2001. This composite shows that the IVM can measure magnetic fields in the solar chromosphere, using the H-alpha line. The IVM data used here is a quicklook reduction. A full science-grade reduction would be better. The Kitt Peak magnetogram measured in the photosphere is shown for reference.
The panels are:
| IVM offband | IVM Line-of-sight field | IVM Transverse field |
| MCCD continuum | Kitt Peak LOS field | MCCD H-alpha line center |
