NB: I already post this in the CN solar system observing forum

 

I have the chance to have a "not too" bad sky.  So I post my last observation of this already nice comet.

The first part of my sketch was done to detect the outher coma, after a rapid calculation based on my sketch (12') I found a diameter of more than 550000 km, (this is ofcourse a minimum), but already 4 time the diameter of Jupiter, not far from the sun's radius !

The second part of my sketch shows two details views of the pseudonucleus with more high magnification, a SWAN filter was used.

Hope everything is ok with you all? During this dangerous period, stay for example ... in your observatory.

 

Michel

Yesterday night (Europe) I found the comet as a fuzzy spot near a bright orange star with mey 80mm Grab&Go.

And with the 16x56 binos it was visible, but barely.

Hi Michel,

 

Thank you for your report.

That comet is changing every day! Interesting to observe sometimes a small secondary tail,  at one side or at the other of the main tail .

 

Keep staying in your observatory

Good luck,

Francis

Interesting to see the differences with a SWAN filter: the comet is smaler but more detailed.

Fine work Michel!  I do not own an observatory so I will just have to build one, buy one, rent one ... or move into yours lol.gif
