| Date/time (local) | Occurrence | Latitude | Longitude | Notes |
|---|
| 04/27/22 01:37:44 | Possibly detected | 42.3872 | -70.6215 | Two unclassified doublets in P2 and 6 and an unclassified singlet in P5 but I’m not convinced these aren’t
HW. |
| 04/27/22 03:07:44 | Possibly detected | 42.3867 | -70.6053 | One classified singlet in P10 and what looks like the start of a faint unclassified doublet right at the end of
the period but that could be HW too. |
| 04/27/22 03:16:05 | Possibly detected | 42.3866 | -70.6036 | Faint unclassified doublet in P1, scoring this as PD for SW since there are no obvious signs of HW
presence. |
| 04/27/22 06:22:44 | Possibly detected | 42.3838 | -70.5862 | Possible unclassified doublet in P14. |
| 04/27/22 06:37:44 | Detected | 42.3832 | -70.5845 | One classified doublet in P6. |
| 04/27/22 07:22:44 | Possibly detected | 42.3815 | -70.5792 | One possible unclassified doublet in P15. |
| 04/27/22 08:06:02 | Possibly detected | 42.3797 | -70.5740 | Multiple unclassified doublets throughout this period and a loud triplet at the end of P3 but the
downsweeps are short. It’s difficult to tell if any of these are true SW downsweeps or just HW. |
| 04/27/22 10:07:44 | Possibly detected | 42.3725 | -70.5561 | Loud unclassified doublet in P1 and unclassified triplet in P2. There are other LF HW downsweeps in this
period and it’s difficult to be certain the doublet and triplet are true SW downsweeps. The doublet looks
convincing and the last downsweep of the doublet could actually be a SW singlet. It’s longer than the
downsweeps before it. |
| 04/27/22 11:07:44 | Possibly detected | 42.3688 | -70.5464 | Classified downsweeps throughout the period but it’s difficult to tell if they’re part of the HW song. The
downsweep at the end of P8 looks like it could be part of a SW doublet that has longer downsweeps than
the others surrounding them. |
| 04/27/22 12:07:44 | Detected | 42.3662 | -70.5320 | Two classified doublets in P4 and 9, both are isolated from the HW song. Other classified and unclassified
singlets throughout the period. |
| 04/27/22 13:37:44 | Possibly detected | 42.3612 | -70.5132 | Possible unclassified doublet in the middle of P10? |
| 04/27/22 14:22:44 | Detected | 42.3602 | -70.5031 | One classified SW doublet in P6 and other LF downsweeps throughout the period but they look more like
HW downsweeps (shorter, steeper, and higher frequency). |
| 04/27/22 18:07:44 | Possibly detected | 42.3513 | -70.4697 | Two possible longer unclassified SW singlets in P2 and 9 and a possible unclassified doublet in P4, but
there are also some shorter LF downsweeps in this period that could be HW. |
| 04/27/22 18:22:44 | Possibly detected | 42.3506 | -70.4683 | One possible unclassified SW singlet in P1. |
| 04/27/22 19:07:44 | Possibly detected | 42.3486 | -70.4641 | One possible longer classified SW singlet in P3, the rest of the downsweeps in this period appear to be
part of the HW song pattern. |
| 04/27/22 20:00:35 | Detected | 42.3457 | -70.4587 | Classified doublets in P2 and 3 that are directly overlapping with the HW song and don’t fit the pattern. |
| 04/27/22 21:07:44 | Possibly detected | 42.3374 | -70.4493 | Possible unclassified doublet in P5 and classified singlet in P6. |
| 04/27/22 22:07:44 | Detected | 42.3343 | -70.4378 | Classified and unclassified singlets and doublets throughout the period. |
| 04/27/22 23:07:44 | Detected | 42.3292 | -70.4290 | Classified and unclassified singlets and doublets throughout the period. Also some faint HW doublets in
pattern in P14. |
| 04/27/22 23:22:44 | Possibly detected | 42.3303 | -70.4273 | One classified singlet in P1 and some others in P2 but it’s difficult to be certain which ones are SW or HW. |

| 04/27/22 02:07:44 | Detected | 42.3870 | -70.6161 | There are some unclassified LF downsweeps in this period, including a few doublets in P8-9 but they look

| 04/27/22 09:07:44 | Detected | 42.3761 | -70.5669 | There are a few classified single downsweeps in this period but they all look a bit steep and like they’re
