GRB 141215A: Swift observation summary

Source 2 has been manually confirmed as the GRB afterglow; data for this object are now available through the main GRB results area for this GRB.

About tiled field analysis.

So far 3 fields have been scheduled for observations. Data are available and processed for 3 of these. The list gives the exposure time used in source detection. If any individual sources were selected for follow-up observations, the source detection is not repeated for the follow up observations and the table below is not updated.

• 20451 — 3.9 ks of cleaned data taken between 2014-12-16 19:01:32 and 2014-12-16 21:03:33
• 20452 — 3.5 ks of cleaned data taken between 2014-12-16 22:11:13 and 2014-12-17 00:12:28
• 20453 — 3.9 ks of cleaned data taken between 2014-12-21 01:23:22 and 2014-12-21 05:01:30
