T Coronae Borealis is a recurring nova -- a thermonuclear bomb that goes off every 80 years. Based its behavior last time, astronomers project that it's likely to explode in April-May. But these things are not completely predictable! www.aavso.org/news/t-crb-p... 🔭🧪

Light curve for the nova T Coronae Borealis. This plot has 4330 Johnson B-band magnitudes (blue diamonds) and 12,734 Johnson V-band magnitudes (green diamonds) all with CCD cameras from 2021.0--2023.5, all binned into 2 day time bins. The usual ellipsoidal modulations (~0.4 mag full-amplitude as a sinewave at half the orbital period) are shown as the thick black curves, one for each of the bands. The variations on all time-scales around the ellipsoidal light curves are normal for T CrB (even back to 1867), with these flickering being larger in the B-band.
