  2. H1743-322 • Discovered by the HEAO satellite in the 1977 when it went up to several Crab • Rediscovered by INTEGRAL on March 21: the brightest X-ray seen by INREGRAL • Detected by the VLA on March 30 • RXTE PCA is observing this source almost daily • X-ray spectrum and timing consistent with a black hole candidate
