... The recently discovered quasar labeled APM 08279+5255 has set a new record as being the brightest continuously emitting object yet known.

The preliminary ALFA pulsar surveys started on August 1st, 2004. In the first day of observations, a new 67.8-ms pulsar, PSR J1928+1746, was discovered: this was the first new pulsar found with ALFA. ... Strangely, the pulsar could not be detected in a 430-MHz observation. This pulsar's apparently unusual spectrum might not be so unusual: 1400-MHz surveys are biased towards finding this kind of object, but the pulsars found in these surveys were not consistently observed at higher frequencies. ...
