| Zusammenfassung |
| We made an effort to understand the associations and relationships between
ground level enhancement (GLE) events and solar flares for the time period of 1986 –
2006. Our results show that, averagely, the GLE-event associated solar flare (~
0.2 x 10-4 w/m2) is much stronger than non-GLE associated solar flare (~ 0.3 x
10-5 w/m2). The findings have also been supported by the solar flare indices that,
averagely, the GLE-event associated solar flare index (~ 35.01) is much higher than
the non-GLE associated solar flare index (~ 4.88). Yet, this association does not
seem to precisely imply that GLE can be occurred by solar flare, so we examined
cross-correlations between GLEs and simultaneous solar flares. We found that most
(~78%) of the highest correlations (r>0.8) took place during X-class flare. There is no
clear indication that the more the time-lag, the less or more is the correlation or
vice-versa. On overall, 50% high correlations took place at higher time delay (-¥65 min)
and ~36% high correlations took place at lower time-delay (-¤40 min) while the
rest (~14%) of the correlations were abruptly high and low at medium time-delay
