Abstract
We report on our analysis of quicklook data (90501304001_v5) of a new 25.5 ks NuSTAR observation of the Galactic X-ray transient Swift J1858.6-0814 (ATel #12151, #12158, #12160, #12163, #12164, #12167, #12180, #12184, #12186, #12197, #12220), which has just become observable after a 3-4 month period of being Sun constrained (ATel #12499).
