Subj: Pisa fan-unit broken

     Ciao a tutti,

     today run 18365 crashed after 2.12h at 8:33 UT due to a broken
     fan unit on Pisa's uVax5 (SM5). The broken component was identified
     to one ball bearing of the fan unit. After two unsuccesful attempts
     (runs 18366 and 18367), run 18368 started w/o uVax5. The fan unit
     was replaced and run 18369 started with full MACRO at 9:10 UT.
     The broken fan unit has already been fixed by Yiannis.

     A presto,

                                  Nicola
