As we said on previous article, on the nights of November 6th to 7th three fireballs could be observed from different stations. Late on the night of November 7th, a similar object to the last one from previous article, could also be observed from Calar Alto cameras. All of these objects are detached fragments from Encke comet.
As it happened last nights, this phenomenon that took place at 23:56, has been studied by Professor Madiedo, from University of Huelva. In this case, the fireball started at about 100 km above the sea level between the coasts of Morocco and Andalucía (south of Spain) traveling northwestward at a speed of more than 100.000 (see the trajectory above).
The fireball could be also observed from La Hita, La Pedriza, La Sagra and Sevilla Observatories.
But it is curious how this object produced a very similar reflection as the fireball that could be observed on the same day but 23 hour before, analyzed on the previous article. They are really similar, but separated by 23 hours, as you can see on the image below.
Below are the videos of the 23:56 event. First is the video from the fireball detection station and then from the south surveillance webcam (in this case, only the reflex produced by the fireball, as the object was very high in respect to the horizon)
Just as a curiosity, see in the video below how the intensity of the fireball produced also reflections on the 2.2m telescope, seen with the camera pointing to the north:
Calar Alto (CAHA) fireball detection station, together with the one at the Observatory of Sierra Nevada (IAA-CSIC) and others placed at different locations in Spain, are part of the S.M.A.R.T. project led by Professor José María Madiedo (University of Huelva) to track that kind of objects. Specifically, Calar Alto (CAHA) station and the one at Sierra Nevada (IAA-CSIC) constitute a collaboration agreement between Professor Madiedo and both institutions.
