The Swift satellite has detected two GRBs over the last two days without sending the usual, fully automatic notices. This is most likely due to an issues with the TDRSS system used to rapidly downlink the relevant data.

The bursts are

- GRB 240101A (the first GRB of 2024!): [Astro-COLIBRI](https://astro-colibri.com/event:1205708)
- GRB 240102A: [Astro-COLIBRI](https://astro-colibri.com/event:1205899)

Let’s hope the full system is getting back online soon…
