Peter Gomory (our PhD student), Ales Kucera, Nils Brynildsen an myself have applied for a new SOHO/TRACE joint operation programme. It was approved as the SOHO JOP 171 and its first runs were scheduled for the MEDOC 12 campaign. We hope that new dat acuired will help us to justify how statistically significant are our results derived from the previous CDS/SOHO data (JOP072).
