Forgot to include the transit times. Any one of these observing times (in UT):

Begin Date: 12/23/2025 13:36 UT
End Date: 12/23/2025 19:10 UT

Begin Date: 12/26/2025 13:19 UT
End Date: 12/26/2025 18:53 UT

Begin Date: 12/29/2025 13:02 UT
End Date: 12/29/2025 18:36 UT

Begin Date: 01/01/2026 12:46 UT
End Date: 01/01/2025 18:20 UT

We need more information to properly address this proposal. You need to provide critical information such as the depth and duration of the transit so we can get an idea of the likelihood of success using AAVSOnet resources. The magnitude range you give doesn't make sense for a planetary transit. Which telescope(s) are you requesting?

The transit lasts for 3.56 hours. The requests above include about 30 minutes on either side of the transit. The star has a brightness of 11.73. There is a mistake in the depth; its 12890 ppm which translates into a depth of 14 mmag so the minimum will be 11.774. The NM BSM telescope should work.

Ian:

Did you previously fill out one of my transit plan templates? That is the most efficient tool to get this underway.
