IPS: Cycle 24 peak now April 2013

Post by VK4GHZ »

FYI, an extract from this weeks ARRL Propagation Bulletin...
(and nice to see Australia's own IPS getting a good plug to a WW ham audience)

Average daily sunspot numbers and solar flux for the week were both higher - sunspot numbers up over
three points to 93.1 - and solar flux up by eight points to 117.2.

Geomagnetic activity was a bit lower, with April 20 the most active day after a coronal hole on the
Sun spewed a solar wind at high speed. The Australian government gave an alert one day prior.

You can subscribe to those emailed warnings at http://www.ips.gov.au/mailman/listinfo/ips-geo-warning.
If you are in Australia, the same service offers an HF radio propagation course.
See http://www.ips.gov.au/Products_and_Services/2/2 for details.

The IPS has predicted monthly smoothed sunspot numbers and solar flux at http://www.ips.gov.au/Solar/1/6 and it
looks like they predict the peak of Cycle 24 exactly two years from now in April 2013.

Well Adam, It Is to be hoped they are correct as the proximity (just after the equinox) can be very exciting---Propo' Xmas to early May if Ol' sol does us the favour, 73 John. VK4ZJB
