report the discovery of two new supernovae and a possible AGN/luminous SN IIn in the Pan-STARRS 1 "3Pi Faint galaxy supernova survey". During the course of the PS1 3Pi sky survey, PS1-1000791 was detected on Aug 14.40 (UT) (Coord: 20:45:13.089 -06:56:11.090, J2000) at g=19.4 and detected again on Aug 19.33 at r=18.64 within 0.9 arcsec of the faint SDSS galaxy (J204513.14-065611.2). ...

The Large Area Telescope (LAT), one of the two instruments aboard the Fermi Gamma-ray Space Telescope, has observed a sharply increasing gamma-ray flux from a source positionally consistent with the high-redshift blazar PKS 1329-049 (1FGL J1331.9-0506, Abdo et al. ...

MAXI/GSC detected a short X-ray transient at the position of (R.A., Dec) = (+160.86 deg, -33.68 deg) = (10 43 27, -33 40 53)(J2000). We obtain a rectangular error box with the following corners: (R.A., Dec) = (+161.09 deg, -34.13 deg) = (10 44 22, -34 07 49)(J2000) (R.A., Dec) = (+160.23 deg, -33.68 deg) = (10 40 55, -33 40 54)(J2000) (R.A., Dec) = (+160.63 deg, -33.23 deg) = (10 42 32, -33 13 44)(J2000) (R.A., Dec) = (+161.49 deg, -33.68 deg) = (10 45 58, -33 40 36)(J2000) This error box indicates statistical error with 90 percent confidence level, and there is additional systematic uncertainty of 0.2 deg (90% containment radius). ...
