General Comments. ( Brief data summary and scan listing )
Global VLBI observations of SN2008D at 5 GHz on 6-7 February 2008 -first 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 two candidate nearby compact sources 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.

Onsala could not participate because the declination motor was broken, The other telescopes performed well. No fringes in the highest subband for Wb is a known limitation. Torun produced regular phase-jumps, a problem that has been seen recently in other experiments as well.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.87 . ERI* = 0.87 . (Ef=0.99, Wb=1, Jb=0.45, Mc=0.94, Nt=1, Tr=1, Hh=1, Ar=1)

plots of the uncalibrated amplitude and phase against time
Comments.
Ef:no fringes in IFs 5-8 in the first scan.
Mc: missed first 22 minutes because of a Mark5A problem.
Jb: had no useful data in IFs 5-8 because of a current problem with "headtsack 2".
