  1. I am very sorry but the delete (and hide) function was used in the way it is not intended. We do not want perfectly good content to disappear as soon as a question was answered for example. Lot's of people find the forums and website trough Google or any other search engine. People can Google something and find an answer in a topic on this forum. I am sure that many new users who have been posting in your topics also found your topics trough Google. I am sorry it is inconvenient for you, that sucks to hear but I cant do anything about it. I even looked if there was a setting that allowed members to hide a topic at a maximum of xxx minutes after creating the topic but there is no such option. There is only an option to restrict members from editing a post until a maximum of xxx minutes after posting. If such a setting becomes available trough forum software updates I will install such a limit as that should accommodate your wish but at the moment there is no such function. Hope you understand our reasoning.
  2. Also, NOAA does not feature CMEs on their model that they do not expect to impact Earth. NASA does. Have to agree with NOAA here. This CME is aimed away from Earth.
  3. That is a good description. When looking at LASCO you will be looking mostly for full halo coronal mass ejection (CMEs that engulf the entire coronagraph). These are either moving directly towards us or away from us. Correlate with SDO and SOHO to see if the eruption was front or back sided. Partial halo coronal mass ejections (CMEs that do not cover the entire LASCO field of view) can still hit us as glancing blows but these are a little harder to accurately predict their path. But combining all the tools like SOHO and STEREO as well as SDO gets you very far. Do dig around in our help section for more info https://www.spaceweatherlive.com/en/help/how-do-we-know-if-a-cme-is-earth-directed-and-when-its-going-to-arrive
  4. If I understood NOAA's document correctly they are only wrong at very very low solar activity. The old sensors just weren't sensitive enough for such quiet conditions. You will see more more variability during quiet solar periods. They also removed a correction factor which has been in place for a very long time. Open the hyperlink from my first post. You can read all about it in the document from the NOAA SWPC.
  5. You are very much correct. They switched to GOES 16 for the GOES primary today. The very low X-ray reading is correct. The GOES-16 X-ray sensor is much more sensitive especially during very low solar activity. It is all explained in the following document. https://www.swpc.noaa.gov/sites/default/files/images/GOES 16 XRS Updates and Status.pdf
  6. Hello and welcome! Not sure what snow has to do with it but you are right, we were at Kp0 for quite a while yesterday and the day before... but it is not in our interest anyway to send out alerts for such occurrences. It is solar minimum and periods with low solar or auroral activity are common at the moment. It is even worse for our Sun: there can be weeks without solar flares or sunspots around solar minimum!
  7. Hello and welcome. Most of the comets that approach the Sun burn up long before they can impact the Sun but it does happen that very large comets survive long enough before they hit the Sun. We can sometimes see comets on coronagraph satellite imagery as they approach the Sun. This YouTube video gives you a great example. I can't really answer your second question but comets do not trigger solar flares or CMEs. Imagine throwing a pebble in the Atlantic ocean. That is comparable to what a comet impact looks like on the Sun.
  8. The data is back now! Nothing to worry about in the end!
  9. That is very much possible. It might be a maneuver that will see them disable such instruments temporarily. That would be nothing out of the ordinary. I am sure the data will be available soon again if that is the case.
  10. Hello and welcome. I also noticed this. Wish I could answer your question but I have no idea.
  11. I am not sure what the question is here but the solar wind is measured by a space craft far away from Earth at the Sun-Earth L1 point something like 1 million miles towards the Sun as seen from Earth's perspective. It is general knowledge that the huge spikes in the solar wind data which can be observed occasionally are a ACE specific issue. When DSCOVR was working, these high density spikes were never registered by DSCOVR.
  12. No worries, didn't at all think you were questioning us! Just thought this was a good moment to explain how we decide whether we report something or not. It's also not feasible for us to write something every single day. At the end of the day, SpaceWeatherLive is a hobby for us that sort of grew to enormous levels. Yes of course you can discuss anything you like! It is great to see users gathering their own information and even informing others if something space weather related occurs. Your intent to donate is very much appreciated. It is people like you that keep us online! Hello Swanny. Welcome! Thank you so much for your comment. I realize there is a wide variety of space weather enthusiasts following us and that is great to see! Glad to see you use SpaceWeatherLive as a resource in a quest to answer your questions.
  13. I understand, but most of our visitors are aurora chasers and mentioning any kind of CME usually results in people getting their hopes up only for them to be crushed when nothing happens a few days later. That's why I choose to only report about CMEs that have a decent chance to impact us and likely cause some kind of geomagnetic disturbance. This CME does not tick those boxes. But of course, enthusiasts like yourself can always (and do!) take a look at the data themselves and form their own opinion. That's the entire philosophy behind this website. Learn about space weather, use the available data and make your own predictions and inform yourself. Us manually reporting about significant solar activity and geomagnetic activity is just one of the many services that we offer but not the main point of the website.
  14. I also noticed this eruption on STEREO yesterday but its lackluster speed and the fact that it can hardly be seen on the available SOHO LASCO images means I am not going to report about it. Its effects on Earth should be minimal if it even hits us. No reason to get people's hopes up, these aren't the type of events that are worthy of much attention.
  15. Just some plasma that tried to escape but got caught by the Sun's gravity causing it to stream back to the solar surface?
