     I note this ATel report from the group led by Ulisse Munari in Italy:

Looks as though folks should be trying to get U (or Sloan u) photometry to follow the changes in accretion rate.

Have a little to submit

We've been doing some u' photometry of T CrB at Madrona Peak.  We just have a few scattered nights over the last several months at this point.  There isn't a comp star u' magnitude available in the AAVSO sequence so will submit a request for one and then get the data submitted.

Thanks for the heads up on this.

U or u band photometry

     The Munari folks evidently _do_ have U or U-B for field stars, as implied by their results, so perhaps they could be asked about it.
