MAXIJ1535-571 was significantly detected as a point source (as expected) in all bands, withpreliminary flux measurements of 220.4 +/- 1.8 mJy at 97 GHz, 226.8 +/- 1.3 mJy at 140 GHz,and 57.7 +/- 1.3 mJy at 230 GHz (statistical errors only). We note that there were sub-optimalweather conditions during the Band 6 observation, and thus more uncertainty is associated withthis flux measurement. This marks MAXI J1535-571 as one of the brightest sub-mm X-ray binarydetections, behind only GRS 1915+105 (Fender & Pooley, 2000, MNRAS, 318, L1) and V404Cyg (Tetarenko et al. 2017, MNRAS, 469, 3141).Our ATCA observations occurred on 2017 September 12, with scans on source from 13:30:20 -13:41:20 UTC (MJD= 58008.5627 - 58008.5704), while the array was in its H168 configuration.We observed simultaneously at 17 and 19 GHz. MAXI J1535-571 was significantly detected inboth bands, with preliminary flux measurements of 133.5 +/- 0.6 mJy at 17 GHz, and 141.6 +/-0.8 mJy at 19 GHz. We note that these are statistical errors only, and estimate a flux calibrationuncertainty of 10%. The radio flux has risen dramatically since our previous ATCA observationson 2017 September 05 (ATel #10711), which showed ~7 mJy at 5 GHz.Radio and sub-mm detections of black hole X-ray binaries typically arise from a compactsynchrotron jet, characterized by a flat to slightly inverted, optically thick spectrum (S_nuproportional to nu^alpha, spectral index alpha>0), originating from overlapping self-absorbedsynchrotron contributions from different regions along the jet.

Given our radio and sub-mm fluxes, the MAXIJ1535-571 jet spectrum is consistent with a single power-law (spectral index of 0.25+/-0.003)extending from the radio band up to ~140 GHz, with the spectral break occurring between the140-230 GHz range. Please note that as a caveat we have not searched for intra-observationvariability in our data; such variability, if present, could affect our interpretation of the spectrum.We will continue to monitor the source at radio and sub-mm frequencies.We thank ALMA and ATCA for rapidly scheduling our observations.10708 Further brightening of the X-ray transient MAXI J1535-571, suggesting thepresence of a black hole10704 Erratum to ATel #10702:MAXI J1535-571 opticalcounterpart coordinates10702 Discovery of the opticalcounterpart of MAXI J1535-57110700 MAXI J1535-571: Swiftdetection and localization10699 MAXI/GSC discovery of anew hard X-ray transientMAXI J1535-571[ Telegram Index ]R.
