    The Minor Planet 2 Pallas will pass within 20 arc minutes of T CrB from June 22-25, with the closest approach of ~12 arc minutes on the evening of the 24th June. Pallas will be travelling from the NE to SW at magnitude nine or thereabouts.

    My thanks to John Greaves for the notification.

    Well done Lars. I wondered if anyone would have a try.

    Clear here until dusk, then cloud rolled in just as I was about to open observatory. Typical!

    I’d forgotten about this. I’ve just had a look and Pallas has just sneaked in to my 30s patrol image from last night.

    Great to see these reports and images. Will be even closer the next couple of nights, so let’s hope for clear skies!

    Thanks for the pointer. Here’s my view of the scene, Johnson B filter:

    Pallas, 2024-06-24 01:18:23.470 UTC, B = 10.31 ± 0.03

    And here’s a colour wide-field image from tonight (Jun 24/25). The bright star at the top is epsilon CrB which is mag 4.2. T CrB should be brighter than this when it goes off.

    I’ve been following this visually and remotely for a while now.

    Image below is from last night (June 24.95 UT), and is a truncated image taken with SLOOH Canary 2 Ultra Wide field 85mm Teleview riding on the main telescope.

    Unfiltered magnitude 9.4CV using the BAA T CrB sequence.

    Four hours of Pallas motion from 22.39 on June 25th to 2.38 on June 26th. I trusted weather forecast and left Seestar running in the garden. T Coronae Borealis is top right.
