... In the hours before dawn, November gives us a chance to observe meteors from two showers. The first that it is thought might produce some bright events is the Northern Taurids shower which has a broad peak of around 10 days but normally gives relatively few meteors per hour. The peak is around the 1 ...

... The left plot shows that the luminosity appears to rise and fall at least once during the phase cycle, but the gap in data coverage between 0.2 and 0.75 makes it difficult to determine if this is a single or multiple variation. The change in Teff is less clear but it also seems to show a pattern sim ...
