Jim, thanks for that helpful information, and thanks for all those contributing on this for this forum. I have been observing T CrB on and off since June 2, 1970! It has always been around magn 10.0, but previoiusly did not have anything like this forum. I recently started looking at T every day, both evening and morning, for obvious reasons. I only do visual observations, so am limited. I am empressed with some of the equipment that most of you have. No doubt T will behave different at different frequencies, but have not seen anything unusual visually. My western horizon is not good, as it looks toward Denver metro area. However, my eastern sky is much bettter, so mornings are better. I can usually get a good view of it down to 10.0 or fainter with my 25x100s.
Hi Jim, since the sun is already at RA 16:30, if you can observe T CrB in the evening, it is already better in the morning. That is good news - observations throughout conjunction! Iām still doing daylight CCD observations with the XPASS system, though only for āfainter thanā limits - I am still working to get down to T CrBās quiescent magnitudes.
Thanks for the ideaā¦
Iām too old and also way too smart to drive to my observing spot, set up, and observe in the cold in the morning. Iām sure some are appeciative of the info to do such a thing, however!

This is unexpected, but I saw T CrB this morning with my 25x100 binocs and put it at 10.8 magnitude! I had it at 9.1 just yesterday morning! Unless I made a mistake. One thing I have noticed since starting my 2024 campaign are numerous artificial satellites passing through the field of view (only about 2 degrees). Every time I look, I see at least one, sometimes 2 crossing the FOV, and sometime they are bright. Total I must have seen at least 10 just this morning, just in my 25x100 FOV. These are distracting and annoying. It was cold - 29 degF and I had to stop looking at 5:45 AM was so cold.
While Iām still doing daylight observing, I found that T CrB is now above my eastern trees at late dawn twilight. I should be able to start reporting positive detections this week.
The weather is turning cold and windy and some snow perhaps here soon. T CrB will soon will be gone to the evening sky for me. The northern EU observers especially have in the past, currently are and are encouraged to continue to follow T CrB as they are able.

I was able to get about 45 minutes of time series data on T CrB this morning. My uncalibrated data shows it at about mag 9.7
I will process and submit the data tonight.

I have been able to get 15-30 minutes on T CrB the last two mornings. Haze this morning. 42N -88W. Looks about 9.7 this morning.
I was out visually observing this morning and put T CrB around 10.0 in my 33x120 Binoās. Definitely fainter than 9.8 and brighter than 10.2. Still waiting for the outburst!
