摘要: Several large solar proton events occurred in the latter half of 1989. For a moderately shielded spacecraft free space, potential exposure would have been greatest for flare which between October 19 to 27, The temporal variations energy spectra at approximately 1 AU were monitored by GOES-7 satellite. These data, recorded and processed NOAA-Boulder Space Environment Laboratory, provide opportunity analyze dose rates cumulative doses might be incurred astronauts transit to, or on, moon. Of particular importance such an event is time development early phases flare, may range over many orders magnitude first few hours. as function entire also predicted. In addition basic shield calculations, rate contours are constructed shelters free-space on lunar surface. 14 refs.
