[Geomag-daily] Daily Report, Tuesday, February 27, 2018, YD 058

[Sauter, Edward]

 All,
The following discrepancies were noted this day:

*Barrow.  There were Bin changes in the H component at 1249 and 1454 UT, on
2/27/18 (YD 058). *

*Deadhorse.   There was a Bin change in the H component at 1249, on 2/27/18
(YD 058). *

*College.   There were Bin changes in the H component at 1236, 1247, and
1323 UT, on 2/27/18 (YD 058).  *

*Sitka.  At 0433 UT, the Z component truncated at 52,500 nT.  This value
was recorded in the Z data until 0435 UT, at which time the Z component had
a Bin change.  This caused a -5.7 nT offset to the Del F plot. All these
events happened on 2/27/18 (YD 058).*

*Fresno.  There was an  Artificial Disturbance from 0417 through 0643 UT,
on 2/27/18 (YD 058).  The  Artificial Disturbance was most dominant in the
Z component and  caused a -3.6 nT offset to the Del F trace.  Mary Jones is
going to investigate.  There was one bad minute value recorded in the F
component at 1949 UT, on 2/26/18 (YD 057).  *

*Tucson.  Because of an internet outage, the Dist, SQ and SV plots have
data gaps  from 0941 through 1044 UT, on 2/27/18 (YD 058). *

*San Juan.  There is a data gap from 0033 through 0041 UT, on 2/27/18 (YD
058). *

*Dist, SQ and SV.  Because of an internet outage, the Dist, SQ and SV
plots for Tucson have data gaps from 0941 through 1044 UT, on 2/27/18 (YD
058).  There is a data gap in the San Juan plots from 0033 through 0041 UT,
on 2/27/18 (YD 058).  *


*Boulder E-Field.  None*

*DST. There is a data gap in the San Juan Dist plot  from 2341 through 2343
UT on 2/26/18 (YD 057).  There is a data gap in the  USGS Dst-1min plot
from 0315 through 0317 UT, on 2/27/18 (YD 058). *
*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,
Ed Sauter
