Io and Europa, double transit.

Io and Europe, double transit!

Although the conditions of seeing are not exactly the best and considering the fact that Jupiter is already moving away, it was still possible to obtain this beautiful record.

Often, the satellites pass over the disc of Jupiter, and we call it transits. Depending on the date of the event, relative to the date of the opposition, the shadow that the satellite projects on the planet during transit may precede or follow the satellite. Timing the beginning and end of transits, as well as the appearance ("ingress") and disappearance ("egress") of satellite shadow is still an interesting exercise, which tests our visual acuity and can be compared with published ephemeris, or obtained From appropriate software.

Transits of the Galilean satellites are among the most beautiful astronomical events that can be viewed by an amateur astronomy.

They are commonplace events, can be seen frequently, but double transits are a bit more sparse and triple much rarer.

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.
