Auroral Propagation Update, VK7 History, RAOTC OTN & LowKey Mags and more.

00:02:44 - Acknowledgement of Country 00:02:55 - Rex VK7MO gave us an update on Auroral Propagation talking about the Kp index getting to 5 for something to happen. Rex outlined that this is just an initial thought and the peaks have been happening in the early morning. 00:06:43 - Rex VK7MO showed a picture of the Sun showing the Coronal Mass Ejection CME going away from the earth on 13 March 2023 which was a one in ten year event. This still caused significant increase in Kp index. Rex outlined there was a difference between the NOAA forecasts Australian Bureau of Meterology - Space Weather Services which is a more localised forecast. 00:12:10 - Andrew Klekicuik has a station at Kingston with a 180 degree camera and saw faint red optical aurora on the evening in question. 00:15:50 - Rex outlined that the theory is radio aurora occurs off the E layer however it is known that the the F Layer optical aurora is red (Nitrogen generated) and the E Layer aurora produces a green visible aurora. Rex showed a photo from New Zealand of this effect. 00:19:00 - Rex showed the difference between the NOAA and the BOM Space Weather measurements. The advantage of the NOAA measurement is there is a forecast. 00:22:17 - We then showed the sunspots currently on the Sun and there are some nice large spots moving towards us. 00:23:42 - Rex then showed the NOAA prediction and the next few days were looking promising. 00:28:00 - Rex outlined that there is some evidence that these events happen on the Equinox. There are a range of element that need to align for these conditions to provide the right conditions for radio propagation. Thanks Rex 00:32:00 - We then moved to some VK7 History and Meg Skegg's father Pat Geeves VK7GV who won a QRP - 1000 Mile per watt award from the ARCI. Thanks to Meg for donating the Certificate/Award to REAST for historical purposes. 00:35:38 - Meg also donated a book titled Crystal Sets and Such things - for the 70th anniversary of 3LO ijn Melbourne. Rex reminisced him receiving the ABC's 3LO broadcast. 00:44:18 - We then reviewed the latest VK-QRP Club - Low Key Magazine. 00:55:46 - We finished with reminders for future presentation and events.
