Dear friends of VLBI, GB042A is now scheduled for mainly a 6cm run over the first 12h. In addition we have a few scans at 13cm during these 12h at Eb, Ro, Go, VLBA. Wb is down during these first 12h. During the remaining 6h of the total of 18h allocated to us we will observe at 13cm with Wb, Ro, Go, VLBA_SC. This change of the schedule has been approved by the EVN and NRAO. Thanks very much for your help. - Norbert Bartel
