The All-Sky Monitor on the Rossi X-ray Timing Explorer has been monitoring the sky in the 1.5 - 12 keV band since late February. The instrument consists of three coded-aperture cameras which can be rotated to view different regions by a motorized drive assembly. Intensities of ~100 known sources are obtained via least-square fits of shadow patterns to the data and compiled to form x-ray light curves. Six orbital periodicities and four long-term periodicities, all previously known, have been detected in these light curves. Searches for additional sources have also been conducted. X-ray light curves for the Crab Nebula, Cyg X-1, 4U 1705-44, GRO J1655-40, and SMC X-1 are reported. They illustrate the quality of the results and the range of observed phenomena.

Discovery of EP J175257.3-351923 as a Candidate Black Hole Low-Mass X-ray Binary
astro-ph.HE 2026-06 unverdicted novelty 6.0

EP J175257.3-351923 is identified as a candidate black hole low-mass X-ray binary from its FRED outburst profile, persistent hard state, truncated disk spectrum with 217 keV cutoff, and high X-ray-to-optical ratio.
