Geomagnetic Activity Plots, Nov-Jan


Gedds est. Kp index for Carrington rotations 2077 and 2078. The 27 day correlation for last rotation was 70,4%.www.gedds.alaska.edu

Forecast 14.1.-9.2. by NOAA

Solar activity is expected to be at very low levels. No proton events are expected at geosynchronous orbit. The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal levels throughout the period.

The geomagnetic field is expected to be at quiet levels through 18 January. Field activity is expected to increase to quiet to unsettled levels, with isolated active periods possible at high latitudes during 19 January due to a recurrent coronal hole high speed stream (CH HSS). Activity is expected to decrease to quiet levels during 20 - 26 January. Activity is expected to increase to quiet to unsettled levels, with isolated active levels possible at high latitudes during 27 - 30 January due to another recurrent CH HSS. Activity is expected to decrease to quiet levels during 31
January - 09 February.

Forecast 31.12.-26.1. by NOAA

Forecast of Solar and Geomagnetic Activity

Solar activity is expected to be at very low levels. No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels during 02 - 06 January. Normal levels are expected 31 December - 01 January and again on 07 - 26 January.

Geomagnetic field activity is expected to be at quiet to unsettled levels during 31 December - 03 January due to a recurrent coronal hole high speed stream (CH HSS). Activity is expected to decrease to quiet levels during 04 - 17 January. Activity is expected to increase to unsettled levels during 18 - 19 January due to a CH HSS.
Activity is expected to decrease to quiet levels during 20 - 26 January.
