Up until now, when I examined my recordings in the morning, Nancay data was available with the current day's timestamp. This rules out the possibility that the date refers to the start of the spectrogram, because these times are still in the future in the morning.

To make it a little more transparent: France and Germany are in the same time zone. Local midnight is one hour after UTC midnight.

At this time of year, our data recording always starts in the evening of the previous day and ends in the early morning hours of the day shown in the Nancay timestamp. You can remember this by saying that the timestamp is on the right of the image and refers to the data to the right.

At the moment, the Nancay images are being uploaded with a significant delay. The responsible employee is probably already on Christmas vacation and someone has to take over. Let's hope that nothing gets mixed up.

Re: Dec 10 2024 Jupiter RCP and LCP - Heliotown
Thanks Tom! Some nice non-Io-A (RCP) followed by some non-Io-C (LCP).

09 Dec 2024 non-Io-A
¿ªÔÆÌåÓýHere's some non-Io-A from the 9th.? Tom's spectrogram showed RCP dominance, thus A instead of C.-- Dave |

Re: solar type III at 1618 UT.
I saw it, several very strong bursts at 35 MHz.

Hi Sabine,

You definitely saw Jupiter. Either non-Io-A'' or non-Io-C. Strange that Nancay didn't see it. Strange that the Nancay spectrogram, ostensibly for the 9th, shows an RCP vertex late non-Io-A-style arc instead of the normal RCP vertex early Io-B arc at around 2100 UTC on the 8th. I do not remember Nancay's file naming scheme -- do they name the files 1) with the date of the start of the observation like everyone else, or 2) with the date of the /end/ of the observation in an effort to confuse everyone, or 3) with whatever date takes up the greater portion of the spectrogram, to REALLY confuse everyone, including themselves? I thought it was #2, but if that's so, their J241209 spectrogram you posted is rather strange. If it's #1, then they saw that vertex late arc at 2100 on the 9th, then that is indeed in a normal non-Io-A area of the phase plane. Just for fun, you might compare their J241210 spectrogram (after they make it available) with this spectrogram of yours from the 10th. -- Dave On 12/10/24 04:23, Sabine Cremer wrote:

09 Dec 2024 Suspected non-Io-C
After an Io-B event, an event occurred in zone "C" which I am cautiously calling non-Io-C. Caution is advisable because nothing can be seen in the Nancay spectrograms, but there is hope because both Faraday banding and weak modulation lanes are visible in parts of the spectrogram.
