Hi all, My name is John Gonyaw. I have recently been attempting to set up a dual dipole antenna and have a few questions about the configuration given my current latitude. I am a bit confused on whether to use a phasing cable for the south dipole, as the manual states one is needed for northern hemisphere observers when Jupiter is at southern declinations, though after checking, I have found it is in northern declinations at my current position. The confusion arises when viewing Fig. 3.8 in the manual that provides an image of the phasing cable attached, but was hoping to clarify that this would not be the case if Jupiter is at northern declinations. Another question arose when choosing the beam patterns for a dual dipole array. I was hoping to gather the most gain, and noticed the evalvation angles given for each were not close to the maximium or average elevation angle of Jupiter for my given latitude. I had found the maximum elavation angle for Jupiter at 40 degrees N to be about 72, and the only close value for elevation angle was 60 degrees. I was curious about how close the two values should be, or if the elevation angle was incorrectly calculated. I have also attached images of the given elevation angle for Jupiter and dual dipole configurations. Thank you! Kind Regards, John Gonyaw

No airglow in the morning and a lot of RFI in the evening but some nice nested teepees. Sabine -- Germany Standard time: UTC +1 hour

Greetings...here are some events from earlier today. I think the capture at 1612:40 UTC is an event. I am seeing what maybe very weak/very distant lightning probably from the southeastern U.S. .....bill......

Good evening: More incredible solar from today. Thanks to Larry, Salvador, Bill and Duane for the heads-up. John

Observations from Grafton, WV. Many solar from today. Probably the most I have caught in a single day so far. ~Duane

Between the event of 120350 UTC previously posted and the event of 2027-2028 UTC I recorded at least 10 events or groups of events. Most occurred between about 1214 UTC and 1500 UTC. Far too many to post. Another extraordinary day for me.....bill....

Good evening, here are third events from this morning...hopefully there are a few more....bill....

Hi All, Thanks for the head's up to all who posted those very nice images of solar on April 02. Going over the data from our Dark Sky Observatory TFD4 array, I ran across this very nice combination of Io-B and a Type III solar burst, all within a few minutes of each other! I will be posting some more images later. Richard

I may be overloading the server by posting all these spectrograms, but I think it is important to document that the Sun was bursting almost continuously for several hours today. Most of it was pretty faint, with a few strong Type III bursts. Richard

Again, the ionosphere kam nicht richtig aus dem Quark. Sabine -- Germany Standard time: UTC +1 hour

Good evening...here are 3 events from this morning. Hopefully, there were more....bill...

Good evening: More and more great solar. Thanks to Bill, Richard, Tom and Duane for the heads-up. John

Observations from Grafton, WV. Did not catch as much as others, but here is what I caught. ~Duane

This was the last strong event record but between the first 3 previously posted and this one there were 6 weaker events. After the 1821:40 event there were 5 more but much weaker. I haven't posted the spectrograms for the weaker events. Anyone interested in the times? A busy day!.....bill....

Hi All, Adding to the ever-growing pile, here are spectrograms from the Dark Sky Observatory of yesterday's solar events. Richard

Good evening: Another good solar day. Thanks to Salvador and Duane for the heads-up. John
