ADMINISTRIVIA
 
     Effective immediately, the Solar Terrestrial Dispatch will begin
providing messages with subject headers in upper and lower case.  All
upper-case lettering in the subject headers will only be used for urgent or
important bulletins, alerts or warnings.
 
 
SATELLITE PROTON EVENT IN PROGRESS
 
     A satellite proton event at greater than 10 MeV recurred at 23:40 UT on
14 June.  The flux increased above event thresholds of 10 pfu and is
presently near 20 pfu.  Decay is expected to occur on 15 June, barring
possible proton flaring from Region 6659 (which is now nearing the western
limb).  This proton event should end later this UT day (15 June), provided
major proton flaring does not develop from Region 6659.
