ARLP013 Propagation de KT7H

Solar flux remains low.  Last week's average solar flux was up only
a couple of points from the previous week.  Geomagnetic conditions
have been unsettled, with several periods with a K index of four.
The worst day was March 21 when the A index was 29 and the K index
reached five.

Don't expect any big changes.  Recurrent coronal holes may cause
disturbances between April 6-9 and 16-21.  During this time expect
brief active to minor storm periods at middle latitudes and brief
active to major storm levels at higher latitudes.

The listing in last week's bulletin of sunspot numbers and solar
flux was correct, but the dates shown were from the previous week.
Below is the same data but with the corrected dates for March 14
through 20.

Sunspot Numbers for March 14 through 20 were 17, 15, 15, 12, 11, 11
and 0, with a mean of 11.6.  10.7 cm flux was 70.8, 70.4, 71, 70.6,
70.6, 69.9 and 69.3, with a mean of 70.4.

Sunspot Numbers for March 21 through 27 were 15, 21, 24, 17, 17, 32
and 29, with a mean of 22.1.  10.7 cm flux was 70.4, 73.8, 72.1,
71.2, 72.5, 71.9 and 71.8, with a mean of 72.
