Global VLBI observations of SN2008D at 5 GHz on 18-19 March 2008 -second epoch. The EVN with Arecibo observed at 1 Gbps with 2-bit sampling, the VLBA telescopes HN and SC at 512 Mbps, 1-bit sampling. Fringe-finders were 4C39.25 and 3C84. The target source as well as one candidate nearby compact source in galaxy NGC2770 were phase-referenced to J0911+3349, within less than a degree. Since the nearby phase-reference source was resolved, the very compact J0919+3324 (2 degrees away) was scheduled for delay-rate referencing.
The Tr phase-jump problem could not be solved in time, disks were not sent to JIVE. The other telescopes performed well. No fringe in the highest subband for Wb is due to a known limitation. Some of the disk packs from Jodrell Bank and Medicina produced low weights during correlation, but the data seems to be good. Effelsberg lost one hour (~2:00-3:00 UT) because of snow. Noto could not observe sources near zenith (20:00-20:45 UT).
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.80 . ERI* = 0.82 .
