Propagation Report from Hannes Coetzee, ZS6BZP12 April, 2009 The sun's failure to produce sunspots is playing havoc with some frequency prediction programs that use stored sunspot values, and of course, with our HF comms as well. The frequency prediction programs tend to give optimistic results and must be treated with caution. The emminent change of season with less energy from the sun reaching the Southern ionosphere is having an impact on propagation as well. 15 and 20 m will provide best opportunities for DX. There is a possibility of 15 m openings towards India from about 13:00 CAT followed by 20 m at 16:00. 17 m may also be very usefull to the east in the afternoons. Contacts with New Zealand and Australia are going to be very challenging. Contacts with Peru are unlikely. Brazil may be worked on 15 m from 14:00 till 18:00. At 16:00 there may be good 15 m openings followed by 20 m openings at 18:00 towards Europe. Contacts with the USA are going to be challenging. 10 MHz is looking promising late afternoon and after dark for the CW and digital enthusiasts. Local conditions are going to be good on 40 m during the day time. 80 m may perform well during the early mornings and late afternoons over the shorter distances, e.g. between ZS5 and ZS6. 30 m may perform well during the middle of the day between ZS6 and ZS1. With winter on its way 20 m is preparing for hibernation but may still give surprising results before lunchtime. Remember that this is only a prediction and that HF has the capability to pleasantly surprise you, but you will never know unless you switch your rig on, listen and also call CQ Please visit www.spaceweather.co.za for further information. • All propagation
