... X-ray sources in galaxies: active nuclei, primodal black holes or microquasars . The last findings in observations of point-like X-ray sources in galaxies are reported. ... A new class of objects has been discovered - the Ultraluminous X-ray (ULX) sources, which could be as black holes of intermediate mass (100-1000 suns), being captured by galaxies and spiralling in because of dynamical friction, or microquasars (SS433-like stars), being orientated "face-on". ...

Noted astro-sketcher Jeremy Perez of Flagstaff, Arizona, made an observation and drawing of Comet PANSTARRS on March 19 while he was out of town visiting family in Elk City, Oklahoma. He reported, "Despite Elk City having lower altitude than Flagstaff and more moisture in the air, the comet was in great form and showing off lots of structure in its tail. I noted three brighter plumes in the main curving section of the tail. There was also a faint straighter edge along the north edge. ...
