[Geomag-daily] Daily Report, 7-18-2018 (199)

[Worthington, Bill]

 The following issues were noted this morning:


*Barrow* - No F data since 10:41 06/16.  A new computer, should be sent
today.  Due to the lack of F data, all derived products are missing.

*Boulder* - There was a F and Delta F spike yesterday at 21:53.

*College* - There is a disturbance, in all components 21:31 to 21:49
yesterday.  My suspicion is that this was unannounced grounds maintenance.

*Fredericksburg* - There is a F and Delta F spikes at 16:53:05, 19:11:04,
and 19:47:18 all probably due to a thunderstorm.

*Fresno* - The three indoor temperatures have now cooled off to their
normal values.

*Guam* - There is grounds maintenance disturbance 04:18 to 04:35 today.

*Tucson* - There are a large number of F and Delta F spikes starting about
23:50 yesterday, lasting to about 10:35 today, probably due to a
thunderstorm.


*ObsRIO Systems* - None.


*Boulder E-Field* - None


*Dst* - There is the usual 0 UT spike, in the 1-minute Dst due to a Kakioka
gap at that time.  There was an overnight gap in the Hermanus data 00:00 to
08:29.

*Dist, SQ, SV* - Barrow is missing, see above.
