  1. The Kp data is publicly available and isn’t being withdrawn from public.
  2. The videos has caused our monthly bill to rise to more than double. Gif’s are also relatively big in size and can further Increase the monthly billing. We disabled videos because of the increase in costs. We want to keep most of the features free to use so we have to take measures. apart from that... as you could see in the gif, there was some ejecta leaving the sun resulting in the magnetic field lines to open up into space and probably reconnect a bit later. But still the sun has magnetic field lines that are open into the interplanetary space and that gap in corona may look more dark when seen from that point of view. Just a guess
  3. That’s a good observation and indeed true, I assume they don’t explain why their model is a bit off in earlier cycles. So we can take that 25th cycle prediction as a bit off course as well...
  4. Currently the right-to-left languages are unsupported, we would have to change/update many items to support those languages. We will add it to our development plans for a future implementation. Once we have the right-to-left support in place, those languages can be added.
  5. An update was released for iPadOS which fixes a display issue on iPads with iPadOS 13.1.
  6. Our current active Spanish translator hasn't made the translation up to date yet, but you can always assist in completing it. If you're up for it, let me know and I'll give you all what you need to know to get started.
  7. On Android we fixed a few bugs after the initial 1.1 release where the app could crash on older devices after purchasing subscription. For iOS we updated the app to match iOS 13 dark mode settings. The app now adapts to the system setting of iOS. If you enable dark mode on iOS, it will be like that in the app as well! If you set it to automatic on iOS, the app will switch automatically as well. How convenient 👍
  8. 10” is big so If the filter itself is also 10” than the view will be very bright. Reducing it will help. I haven’t build a solar filter for my Orion 12” Dobson because it was too big and more risk of damaging the filter. I had an old 11cm scope which was good enough for the Sun but still no granules. But from what I’ve read you should have an extra filter on your ocular which further reduces the light to reveal details. Take a look at https://www.astromarket.org/filters/blocking-filters/15_15_36/m,Baader-Planetarium
  9. Mercury transit is really great to view through a telescope! I witnessed it one time and a rare Venus transit. The kids at school will sure like it!
  10. With a normal white light filter of Baader I also never saw any granules of the surface. Most scopes are way too big for the vast amount of light of the Sun, although the filter does filter enough it's still very bright. To really see granules, a H-alpha solar telescope is a better fit. You got H-alpha filters for scopes as well but really expensive or the 'cheaper' Coronado PST telescopes. To see sunspots, it ain't the best time indeed 😉 hopefully the new solar cycle will be here soon to get something worth viewing
  11. We just released a big update for our SpaceWeatherLive app on iOS and Android! - You can now select which space weather alerts you want to receive. - Tired of the ads? Remove them with an in-app subscription. With your help we can keep our services online and keep you up to date with the latest space weather events. more information in the news section.
  12. Was the compass far away from any electronic device and or magnets? These can influence the needle of the compass. If it was a digital compass, there is always interference of the device itself.
  13. It’s always the same at the end of a solar cycle, always a vast amount of scientist with different outcome on the prediction of the next cycle. The methods they use are always based on good research and data but still, the inner workings of the Sun are still so much unknown that it can’t be predicted in a perfect way. It’s good that there are multiple predictions to see what methods they used and how they think it will evolve. It can improve the predictions of others and improve them. With the sc24 predictions we started the cycle with two versions because they couldn’t agree and “the board” chose the stronger and a weaker cycle for sc24. It was untill after the long minimum that they abandoned the stronger cycle. Just to say that there is no good method for a prediction and you better wait and see what time brings...
  14. Nice to see a new SC25 region with some activity.
  15. We currently have one active Spanish translator who's done most of the work except the help section.
  16. Solar activity causes geomagnetic storms. It does not cause a reversal of magnetic poles of the Earth. The stronger solar wind of a strong coronal mass ejection pushes the magnetic field lines of the Earth inwards on the sunlit side. Please read our help section to learn more about solar storms and the effects they cause.
  17. What I meant with "latitude seems too high" is that new cycle spots mostly appear around 40° latitude, the latitudes you had in your pictures was higher and thus not very plausible that regions would start appear there. I found an other diagram with pretty recent data: Also a very good research study on the solar cycle: https://www.researchgate.net/publication/227138551_Long-Term_Solar_Cycle_Evolution_Review_of_Recent_Developments
  18. New spots are only defined if they are visible in white light or on the HMI instrument of SDO, not before. If the spot(s) still exist after 00:00 midnight a new region number is officially assigned.In the cases above, there was no visible spot in white light and/or HMI instrument. The butterfly diagram you posted is an older one than the one J. Janssens has and is a bit more detailed 😉
  19. The butterfly diagram gives the sunspot regions latitude in the y and time in the x axis. Where sc24 fade out more and more sc25 regions would take over. I didn’t find an updated chart 😕 (most recent is that of Jan Janssens of February 2019) The images with a brighter zone is not a zone where a region would appear, latitude seems too high too. Just some granules of the Sun, nothing fancy. I guess HMI didn’t give anything for that place either?
  20. I did look but it's still in my opionion mostly guesswork and time will tell who was right 😉 . As long as the scientist don't know the exact inner workings of the Sun, the predictions of solar minimum and maximum will be very variable. Before the previous minimum there where a lot of different oppinions of many scientists and it turned out that half wasn't right. Let's evaluate in 6 months where we are 😉
  21. We don't provide downloadable exports of our archived data, please use the data from the official organisations. Kp/Ap data can be retrieved from the Potsdam website where the finalized official Kp can be downloaded in a few formats.
  22. Both new regions are still from old cycle, if we where past minimum, we would see more SC25 regions appear and that's not the case yet. Still old SC24 regions emerge so it still looks that the minimum has yet to come.
  23. That's because the source is different. May 29th had no visible sunspot regions and no spots, as well as the day before and after. SWPC gave out a SN of 0 which still seems corect. No region was numbered as well so it must have been a shortlived one that was registered in some stations of the SILSO network that record the SN. SWPC has their own counting 😉
  24. It wasn't meant to be offensive. One of the questions was what the abbreviations where on the right side of the image, it was all explained on the magnetometer page and thus I thought you might have not seen the "details" button that reveals more information about those stations. That's why I mentioned that first. Second, I had a clear explanation below the first paragraph to give you more information on the things you asked about to digg in deeper then the information on the magnetometer page. If I was offensive, I would have stayed with one paragraph, but I did my best to give you more detail.
