Photometry of Don Loftus' Seestar image from last night 24 June 2024 at 00:19:04 (EDT) gives the following results:

T CRB,2460485.679789, 9.398, 0.004,TR

T CRB,2460485.679789,10.230, 0.004,TG

T CRB,2460485.679789,11.610, 0.005,TB

The Tricolor Green (TG) magnitude = 10.230 most closely approximates the star's visual magnitude. The star's color index = TB-TG = 1.380. Anything greater than 1 signifies a red star. The red giant star in the T CrB system overwhelms the light of the white dwarf. We are waiting for the outburst of the T CrB, the Blaze Star.

Have created an observer code with the AAVSO. Thanks for the help, Andy.

Matt, that's a cool way to check the field. How did you take the photo using your mobile phone?

Attached is a light curve that shows our observations (Andy, Mike, & Matt) of T CrB over the past 90 days. T CrB hasn't changed much, although it has brightened slightly in the past week or so. HOA = Andy, PMADA = Matt, TMIE = Mike. Don could register at AAVSO to get his initials and data posted online.
