Many thanks to former LRS member Mike Senior GM3PAK, who lives with his XYL Marion GM1DCB on the isle of Islay, for this nice photo of the Aurora on 21 March 2017. Did anyone work anything via AU?  

Another aurora is forecast for the following evening but it will probably not be visual in Edinburgh due to forecast cloud and rain.

Following John Cooke's talk on amateur radio applications for the Raspberry Pi microcomputer at the March 8th meeting (see report below), John now reports that he has successfully received the FUNcube-1 satellite using a Raspberry Pi 3. He writes: 'Just managed the next stage of my satellite project successfully. It uses the DVB-T dongle I showed at the talk, and the Raspberry Pi 3 (at present). I'm really impressed that the satellite is so easy to receive with the dongle- I'm using a turnstile antenna for 145.9MHz outdoors'.
