Marginally detected in 2005, an XMM- Newton observation in 2013 set a clear detection im- plying a flux increase of at least a factor 3.8. Simulta- neous observations at other wavelengths showed the quasar still extreme X-ray weak, with a peculiar spec- tral energy distribution (SED) and unique features in the UV spectrum. We propose that PG 0043+039 is a genuine X-ray weak quasar. To probe this hy- pothesis and to test alternative emission scenarios (ADAFs, missing corona (Ricci et al., 2020 ApJ 898, L1), cyclotron-emission (Kollatschny et al. 2015, A&A, 577, L1)) this unique source deserves further, deeper, observations, aiming to establish its X-ray spectrum, its optical to hard X-ray SED and new con- straints on its variability. Our proposal is to observe PG 0043+039 quasi-simultaneously (2 days) with XMM-Newton (100ks + 20ks), NuSTAR (60ks) and HST (2 orbits). We will arrange quasi-simultaneous observations with the ground 10m Hobby-Eberly Telescope in Texas and with the 10m SALT Telescope in South Africa. ------------------------------------------------------------------------------------ Observations Description ------------------------ PG 0043+039 is the most X-ray weak quasar known. We plan to observe PG0043+039 quasi-simultaneously with HST and XMM. We intend to take a FUV spectrum with COS/FUV G140L(1105) for the first orbit. The second orbit is devoted to a NUV spectrum with COS/NUV G230L. We observed this quasar before with COS/FUV G140L(1105) on July 18, 2013.
