wpo - quasar images - look-back time in billions of years [3]
2000 Apr 29: More quasar fields recorded - most with a redshift >z2 or >11 billion lightyear range shown as a thermometer at the base of each image. Interestingly 3C279 was reported on 2000 May 5 as in 'outburst' on BAA webpage. Q1304+295 in Coma Berenices is at the limit of detection but a very weak image was recorded on the meridian at ~70o altitude and perhaps brighter than the quoted [Sky Cat 2000] magnitude of Mv19.4 .
