1 gennaio 2014, il Sole comincia l'anno col botto! Il gruppo di macchie AR1944, uno dei più grandi del ciclo, si affaccia sul lato visibile del Sole. Qualche giorno più tardi, genera un flare di classe X 1.2, con conseguenti tempeste magnetiche ed aurore sulla Terra.

Ma in questa ripresa siamo ancora al primo gennaio, ora di pranzo. Il Sole mostra una piccola protuberanza che si evolve rapidamente. Setto la camera per uno scatto al minuto e vado a pranzo.

Dopo un ora e mezza controllo gli scatti... La protuberanza si è espansa ed allontanata dalla superficie solare, generando una gigantesca espulsione di massa coronale (CME).

La presente CME si staglia al di sopra della cromosfera per circa 220mila Km, e raggiunge approssimativamente, al termine della ripresa, una lunghezza complessiva di 480mila Km.

Un’energia per noi impensabile rilasciata nel giro di pochi minuti, una danza vorticosa di particelle ionizzate, sotto forma di plasma, che fa espandere il materiale ad una velocità calcolata di circa 58000km/h. Spinte via per sempre dalla cromosfera, alcune saranno poi catturate dalle magnetosfere di altri pianeti e termineranno la loro corsa sotto forma di aurore.

Questa è una delle riprese che preferisco di più in assoluto, venuta per caso e totalmente inaspettata. È il bello della nostra stella...non cessa mai di stupire chi la osserva!

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
