16.08 Vmag 2020-10-09.4668 -

16.08 Vmag 2020-10-09.4668 - It's in my observatory scheduler now so if the weather plays ball I can keep submitting measurements.

multiband photometry?

Can you do multicolor photometry? Using B, R or I filters too? Or time series?

I tried to observe it with iTelescope.net facilities from Siding Spring, AU, but it was not visible from the obseervatory :(

Yes I just ran out of cloud

Yes I just ran out of cloud free night last night.  I've scheduled B,V,R,I at a high priority so they will run on the next clear night.  I will monitor each clear night for the next while and see how it's changing.

Have got a few images last night

Have got a few images last night remotely from Chile. Data are with the AAVSO. Airmass is from about 2 to 2.6. Will continue observing this transient the upcoming clear nights.

~17Vmag now.

I managed to get one set images last night in BVRI.  It's pretty low in the west at astronomical dusk so it is a challange.  It's ~17Vmag now.  Even with double the exposure in B (600s) I couldn't get enough S/N to get a B value.  I'll try and get some longer exposures over the next few days but it's a tricky one.
