With reference to ATel #1988 (and references therein) on the optical and near-IR brightening of the blazar PKS 1510−08, the GLAST-AGILE Support Program (GASP) of the Whole Earth Blazar Telescope (WEBT) reports that the source has further brightened by almost 1 mag in the last 3 days, reaching R = 14.35 0.03 on March 27.1. As far as we know, this is the brightest optical state ever observed for this object. Observations at all wavelengths are obviously strongly encouraged.
