[Geomag-daily] Daily Report, Monday, July 23, 2018, YD 204.

[Sauter, Edward]

 All,
The following discrepancies were noted this day:

*Barrow.  The Total Field data is still absent due to a malfunctioning MXE
A**cquisition computer**.  We are awaiting delivery of a replacement MXE.
 Therefore all derived products are absent: D, Del F, X, Y, Dist, SQ, and
SV.  *

*Deadhorse.  There was a loss of Variation data (H, E, and Z components),
from 1915 through 1455 UT, on 7/20/18 (YD 201).*

*Fredericksburg.** There was a data loss from 1323 through 1351 UT, on
7/23/18 (YD 204), due to an equipment **swap out**. There was an *
*Artificial** Disturbance following this time, through 1408 UT, as the area
was cleared. *

* Tucson. There were bad Total Field Values during minute 0132, and 1139
UT, on 7/21/18 (YD 201).  There were data gaps in the Dist, Sq, and SV
plots from 0033 through 0149 UT, on 7/23/18 (YD 204), most likely caused by
a drop in the internet connection.*

*Stennis.   There were data gaps in the Dist, Sq, and SV plots from 0051
through 0114 UT, on 7/21/18 (YD 201), and from 1013 through 1119 UT, on
7/22/18 (YD 202), most likely caused by  drops in the internet connection. *

*Dist, SQ and SV.   As mentioned above, the Dist, SQ and SV plots from
Barrow are absent.   Also, there are data gaps in the Dist, Sq and Sv plots
at Tucson from  0132, and 1139 UT, on 7/21/18 (YD 201), and at Stennis from
0051 through 0114 UT, on 7/21/18 (YD 201), and from 1013 through 1119 UT,
on 7/22/18 (YD 202).  These data gaps are most likely caused by drops in
the internet connection. *

*Boulder E-Field.  None*

*DST.  There is an offset in the San Juan Dist plot at 1547 UT, on 7/22/18
(YD 202).  This caused a corresponding offset in the USGS Dst3-USGS plot
and a temporary offset in the USGS Dst-1min plot at the same time.  **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.
