47 million years ago, a giant star from the Messier 77 Galaxy in the direction 
of the constellation Cetus collapsed gravitationally.
In a few seconds, it nucleus undergoes a cataclysmic implosion that raises
it temperature to several billion degrees Kelvin and whose shock wave
spreads to the outer layers of the star making it to explode.
It's just a type II Supernova.
The giant temperature and pressure generated by this explosion are large enough
to produce heavier chemical elements such as gold and platinum inside the star.
The supernovae are so bright that if it is placed at a distance of 33 light years
from us it would turn night in day for a few weeks while the Sun would be
at the limit of visibility in cities as a magnitude star +4.8.
On the night of November 24th, 2018, the US-based DLT40 observes the Supernova
and issued an alert for astronomers communities.
Supernova gets the name SN 2018ivc and in a few hours it is seen by both
professional and amateur astronomers.
Last night (November 30th, 2018), we went out to catch the SN 2018vc and test
the equipment in very cold environment (-9 CO) and under the urban sky conditions
in Bucharest, Romania.
The setup was installed outside at the Astronomical Institute of
the Romanian Academy and the commands were made remotly from the inside of
the Planetarium Hall.
The image below is the result of a stack of 40 frames of 25 second exposure each,
at a focal length of 2235mm.
At the center of the frame is the M77 spiral galaxy and is annotated
with SN 2018ivc Supernova position.
To the left, we have a reversed-color galaxy detail that better reproduces
the galactic halos and a detail in the color palette in which it is seen that
the apparent brightness of the SN 2018ivc supernova is comparable to that of
the galaxy it belongs to.
We thank the Astronomical Institute of the Romanian Academy for the support. Technical details: Software: remote control and full acquisition in Hyperion Prism Advanced.

    About Me

    Astroclubul Bucuresti is an amateur astronomer association in Romania. The association is continuing the tradition of amateur astronomy in Romania, which started in 1907 with the founding of the first “Romanian Astronomical Society". We are amateur astronomers mainly from Bucharest but we also have members in Melbourne (Australia), Auckland (New Zeeland), Cambridge (UK), Paris (France), Silistra (Bulgaria), Canary Islands (Spain). The main interests of our organization are visual observations, astrophotography, variable star observations, spectroscopy, outreach in schools and popularizing astronomy to the general public and organizing lectures and astronomy training courses. Astroclubul Bucuresti also regularly cooperates with the Astronomical Institute...
