M51 with SN2011dh

Just a personal record of this supernova while weather permits. Unfortunately seeing was really poor and clouds roll in quickly after the object passed meridian last night.

Congratulations!

I went to PTC last night, transparency was quite good while the Polaris was not visible. The clouds rolled in after the equipment was set up.

I think the message of today's newspaper is not correct.

它這樣的光度可以維持多久呢?

Took more images of the object on 9-Jun. Sky conditions were similar: transparancy good, seeing poor. Managed to get some RGB data as well. Also used LPS-P2 filter this time. Below are the LRGB and L versions of the image.

I noticed that the SN seemed to have brightened up! Not sure if this make sense at all. Or was it affected by the use of the LPS filter. Did some rough measurement using MaxIm. I got a reading of Mag 14.5 on 5-Jun and Mag 13.4 on 9-Jun.

Yes, this time the SN is obviously brighter than the one you took 5th Jun.
