← Back to lettersSir,
We have information concerning the criticisms you addressed to us regarding a possible error that would be in the circular letter sent in May to many individuals of Spanish nationality. The paragraphs in question read verbatim:
- Absolute visual magnitude: 14.3
- Apparent visual magnitude: it will surely decrease due to the interposition of a large cloud of cosmic dust located at 3.682 by
Therefore, at a distance from our planetary system (calculated at 3.682 parsecs, about 12 light-years), we have discovered towards our IUMMA a huge static cloud of cosmic dust, it is likely that the absorption exerted by this mass further reduces the brightness you observe (that is to say its apparent magnitude). This is why we told you that it would be between 12 and 13 (let's not forget that the number expressing magnitude increases gradually as the noticeable brightness perceived by the eyes decreases).
We still do not understand where we may have made a mistake. Perhaps by reading the document quickly, you understood that the magnitude 'reduced' from 14.3 to 12 or 13.2 in c
