Just below 16 last night here, in hazy skies.

Hi!

Down to about 17, clear filter, here last night. No sign of a (final?) rebrightening.

Thanks Magnus. Yes, the fourth rebrightening is now underway.

Hi!

Very hazy and thin clouds here yesterday. I captured one frame of UX Boo, but I do not trust the measurement. However, it indicated that it is still bright (my measurement was 11.4 with an error of…. 2.4 magnitudes. So I do not report it. But seems like a somewhat longer peak this time. Hopefully someone else caught it last night – Ian?

Hi Magnus,

Unfortunately not. The weather has been poor here (I can’t get it from Spain anymore). Looking promising for tomorrow (Monday) evening….

Cheers
Ian.
