BB325DC / GCN 614415 / GRB 141005A


GCN Report

UVOT took a finding chart exposure of 250 seconds with the U filter starting 93 seconds after the BAT trigger. No credible afterglow candidate has been found in the initial data products.

D. Perley with the P60 RA = 19:24:22.392 dec = +36:05:42.26 (J2000, +/- 0.3")


Haven't yet looked at the correlated data.


From Kiri:

This one was broken into 3 jobs:


Source Name: J1936+3642 Source RA: 5.133 Source Dec: 0.641 ** 12 rejected detections


Source Name: GCN614415 Source RA: 5.081 Source Dec: 0.630 ** 20 rejected detections


Source Name: B2020+28 Source RA: 5.335 Source Dec: 0.505 ** 5 detections marked as "pulsar", all with DM = 24.19 ** 2 rejected detections

Is this helpful?


Correlated Data

On 13 Oct made the following request to change the phase center:

There is an updated position for this GRB.

Can you please correlate the BB325BC scans of GCN614415

With the following  ra/dec?

RA = 19:24:22.392 dec = +36:05:42.26 (J2000)
