    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

    Column 1: Object Identifier;

    Column 2: Julian Date;

    Column 3: Magnitude;

    Column 4: Error;

    Column 5: Filter

    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.

    Matthew, Andy, thanks so much for sharing your observations from last night. I've been clouded out... a sort of pre-monsoonal flow has taken over northern New Mexico. I might get an observation in tomorrow night.

    Relieved to see the 12-13 minute arc separation prediction between TCrB and Pallas was not miscalculated. Just sad I wasn't able to make a time lapse of it.

    A quick mobile phone check from last night out at CAV, as expected, no nova
