NASA has highlighted one of Emili Vilamala's photographs from the report Lluvia de globos de los cirrus floccus, published in Las Fotos de los Lectores de La Vanguardia last Friday, July 7.
The snapshot was taken during the celebration of the European Balloon Festival in Igualada and shows the flight of the balloons between the cirrus floccus clouds and the waning moon.
The photograph has been selected by NASA within the Astronomy Pictures Daily section of its Instagram account, where it selects the best images in the world of astronomical and meteorological phenomena.
Cirrus floccus are shaped like small rounded tufts and often with tails. On this occasion, they were accompanied by the balloons and the waning moon, "a moon that was very visible early in the day," explains Emili Vilamala, author of the photograph.
The name "cirrus floccus" is derived from Latin and means "a lock of wool." And it is that they appear as small wisps of clouds, generally with an irregular base.
