May, 10th : two supernovae at once !...

Comet SWAN is gone, at least for southern observers, but we have been granted as soon with the spectacle of two supernovae visible at the same time, a bright one in a faint galaxy, and a fainter one in a bright galaxy !

The first one is SN2020hvf, a type Ia supernova happening in the remote galaxy NGC3643, in Leo. At a magnitude of 12.4, this is the brightest supernova visible in over a year, outshining the galaxy itself !

Full view, with the supernova marked on the right one. The host galaxy is barely visible to its upper right. The bright spot at the upper left corner is the much brighter galaxy NGC3640.

Closer view, showing the host galaxy NGC3643 (centre), with the supernova to its lower left.

The next one is SN2020jfo, a type II supernova at an estimated magnitude of 14.5, happening in the magnificent galaxy M61 in Virgo: strange enough, supernovae in beautiful galaxies are quite rare, so this one is highly appreciated by observers...

Full view, with the supernova marked on the bottom one.

The closer view below shows the details of the complex structure of the host galaxy, with the supernova to its inmediate right.
