Hello Everyone, SpaceX is proposing to orbit 19,440 Starlink internet satellites at the very low altitude of 350 km. These would be quite bright but most would be eclipsed by the time that twilight turns to darkness. The US Federal Communications Commission is considering the company’s request. One of their concerns is the impact on astronomical observing. In the article linked below I predict the magnitudes and distribution of these spacecraft across the sky. https://arxiv.org/abs/2406.16589 Meanwhile, Richard Cole informed me that the satellites in Starlink launch 10-1 have stopped orbit raising at about 350 km. Their designations indicate that they are not Direct-to-Cell spacecraft. So these could be the first very low altitude internet sats, possibly in a testing state. I welcome observed magnitudes for these objects. The reporting format that I prefer is given in the article linked below, but I will try to work with observations in other formats. https://arxiv.org/abs/2208.07834 Best regards, Tony Mallama <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> Virus-free.www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2> _______________________________________________ Seesat-l mailing list https://lists.seesatmail.org/mailman/listinfo/seesat-lReceived on Thu Jun 27 2024 - 05:13:52 UTC
