DESCRIPTION:Minifilaments are miniature versions of filaments\, first obser
 ved in H-alpha filtergrams of quiet Sun. Recent studies have showcased the
 ir association with small-scale eruptive events\, highlighting their impor
 tance in energetic processes of the quiet Sun. We present the first detail
 ed study of such an event\, using high-cadence\, high-spectral resolution 
 imaging observations. The minifilament formed between small-scale\, opposi
 te-polarity magnetic concentrations and erupted within an hour after its a
 ppearance in H-alpha\, exhibiting a twisted\, thread-like structure. Its e
 ruption took place in two phases (slow and fast)\, producing a coronal dim
 ming\, while part of the erupting material returned to the chromosphere. T
 he observed similarities to large-scale filament eruptions indicate the ac
 tion of common mechanisms. Their properties\, combined with their abundanc
 e in quiet Sun\, constitute minifilaments ideal targets for the new ground
 -based solar telescopes.\nVortragender: Ioannis Kontogiannis
