  We have collected data spanning seven years of observations of the magnetar
4U 0142+61 in the infrared, optical and soft X-rays. These combine our own
observations and analysis of archival data. We find that the source is variable
in the optical, in contrast to what had been previously reported, that the
K-band flux can vary by over a magnitude on the time-scale of days, and that
the X-ray pulsed flux is not obviously correlated with either the total X-ray
flux or infrared and optical fluxes. Furthermore, from multi-color photometry
of the source within single nights, we conclude that there are two separate
components to the infrared emission. The overall picture is unclear, and
prompts the need for further, more frequent observations.
