We report the detection of a radio burst from the newly discovered repeater FRB 20240114A (ATel #16420) with the Northern Cross (NC) radio telescope. Observations were carried out with a 16 MHz bandwidth at a central frequency of 408 MHz, with a 14.468 kHz channel width and a 138.24 μs sampling time. We monitored FRB 20240114A for 7 days since February 28th 2024, using 16 cylinders of the North South arm of the NC, 26 mins per day with similar starting times dictated by the transit of the source. The coordinates used for the observations were RA: 321.9 deg, Dec: +4.35 deg (J2000), as in ATel #16420.
The burst was detected on February 1st 2024 at 11:49:06.081 UTC (MJD: 60341.4924314915, Barycentric Time of Arrival at 400 MHz) and has 35 ± 3 Jy ms fluence and a width of 4.6 ms.
The search was performed using Heimdall (Barsdell et al. 2012) and FETCH (Agarwal et al. 2020) spanning a DM range between 400 and 600 cm-3 with Signal to Noise Ratio > 7. The best fit DM obtained for this candidate is 527.7 ± 0.8 pc cm-3, consistent with previous burst detections from the same source (ATel#16420, #16426, #16430, #16432. #16433). The link below shows the waterfall plot for this burst.
The monitoring of the source is still ongoing.
