• ATel 1530: Swift Observations of NGC 1313

  We report on three X-ray sources within the spiral galaxy NGC 1313, namely X-1, X-2, and SN 1978K. The sources X-1 and X-2 are well-known ultra-luminous X-ray sources (ULXs). ...

• ATel 1529: XMMU J005527.6-721059 = CXOU J005527.9-721058: Be/X-ray binary pulsar in the SMC or background AGN?

  We report the detection of a point source designated XMMU J005527.6-721059 in an archival XMM-Newton observation in the direction of the SMC from March 2002. ...

• ATel 1528: Swift detects an X-ray and optical outburst from a Galactic source probably associated with 1RXH J173523.7-354013

  The Swift team and collaborators report on the detection of an outburst from a previously unknown Galactic transient consistent in position with the ROSAT source 1RXH J173523.7-354013. ...

• ATel 1527: XMM-Newton slew-survey counterpart to the INTEGRAL source IGR J18307-1232

  We report the first X-ray identification of the source IGR J18307-1232 which was reported in the 3rd INTEGRAL IBIS/ISGRI soft gamma-ray survey catalog (Bird et al. ...

• ATel 1526: Discovery of Supernova Candidate by CFHT-COVET

  Continued search by CFHT-COVET (ATEL 1487, ATEL 1519) reveals another optical transient on UT 2008 May 13.366 : Name | RA(J2000) | Dec(J2000) | Mag (r') | Offset from host | COVET-080513A | 12h42m21.09s | 11d59m49.5s | 21.3 | 0.6"W, 0.5"N | The offset from the barred spiral host suggests this is a supernova candidate. ...

• ATel 1525: Continued Radio Non-Detection of SN 2006gy with the VLA at 8.4 and 43 GHz

  We continue our VLA monitoring of SN 2006gy, which is among the most luminous supernovae ever seen. On 2008 Feb. 10.0 UT, no radio emission was seen at the optical position with the following 3-sigma upper limits: 8.4 GHz: 0.25 mJy/bm; resolution 1.4", 43 GHz: 0.55 mJy/bm; resolution 0.3". ...
