[Geomag-daily] Daily Report, Wednesday, April 6, 2018, YD 096

[Spritzer, John]

All,
The following discrepancies were noted this day:

BRT - is down for updates to the system. Brendan will notify the group when
system is up.

TUC - There is a gap in the Dist, SQ and SV plots at Tucson on 4/6/18 (YD
096) at 08:46:00 - 09:09:00 (UT). The data gap may have been caused by
Internet outages.

DED - There were bad total field values recorded as spikes on the Delta F
channel during minutes 00:41 and 11:33 on 4/6/18 (YD 096).

GUA - There was a spike and anomalous activity on the Delta F channel from
approximately 09:30:00 - 13:45:00 (UT). Probable source is suspected to be
grounds crew maintenance.

DST -  There is the daily offset in the USGS Dst-1min plot resulting from
the corresponding data gap in the plot for Kakioka at around the end/start
of each day.

That's all,
 John Spritzer
