TITLE: GCN CIRCULAR NUMBER: 4997 SUBJECT: No OT 060420 in MASCOT images DATE: 06/04/22 15:45:00 GMT FROM: Alain Smette at ESO/Chile A. Smette (ESO Chile) reports: The Mini All-Sky Cloud Observation Tool (MASCOT) located at ESO's Very Large Telescope Observatory, Cerro Paranal, Chile, (http://www.eso.org/instruments/mascot/index.html) obtained 90 s images simultaneously to the CONCAM images reported in GCN 4995. Comparison with previous MASCOT images indicates that there is no optical transient at the reported location of the proposed OT060420 in images taken between 2006-04-20T00:15 and 2006-04-20T00:36 UT. Although conditions were cloudy, limiting magnitudes are similar to the CONCAM images. MASCOT images are available through the ESO archive: http://archive.eso.org/eso/eso_archive_main.html
