A deep partial eclipse of the Moon,
a stellar explosion in a distant galaxy,
the return of an historical comet,
and a farewell to planet Pluto...

Just a regular, quiet November month at the observatory...

Planet Pluto is not really a popular target among amateur astronomers, since it shows only as a tiny white dot, undistinguishable from the many surrounding stars. However we wanted to take a look at it, remembering that this is a fascinating planetary system of its own... Also, while standing in Sagittarius, Pluto is about to disappear behind the Sun, so it cannot be watched again in good conditions until July, 2022.

The two pictures below, taken at an interval of 24 hours, show the star field around Pluto : hence the planet is the only dot that moved in the meantime... Can you spot it by yourself, above the centre of the field? If you do, you are repeating the procedure that led to its discovery in 1930...

Just in case, here is the same field, with the planet marked... (click to enlarge)

Comet 6P/ d'Arrest, discovered in 1851, is a short period body (some 6.5 years), so it can be witnessed several times in a lifetime, although some of the approaches are not favourable to observations. On November, 24th, we succeeded to capture it, in Piscis Austrinus, at a respectable magnitude of 10.2, an easy target under clear skies.

The view below shows the brighter nucleus, slightly shifted (it moved some 15 arcsec. during the exposure time), all embedded in a subtle greenish coma.

A few days ago, the Type Ia supernova SN2021aefx has been discovered in the galaxy NGC1566 (Dor): both the galaxy and the supernova are bright, so the resulting view is quite spectacular...
We took the above picture on November 24th, when the supernova was shining at a visual magnitude of 12.5, that is quite bright for such a distant event (estimated over 60 million light-years).
On this view we can appreciate the two main spiral arms of the galaxy, with the supernova standing to the right of the upper arm (see the marks on the small icon at left).

On November, 19th, at dawn, there was a partial eclipse of the Moon visible in almost all Americas, reaching up to 97% of the lunar disk covered, hence giving a nice display of contrasted colours.

Eclipse begins, the eastern limb already appears darkened :
Eclipse progress, now displaying the neat and curved border of the earth shadow :
Eclipse close to its maximum, with the usual orange coloured shadow of Earth :
