A Preliminary Comparison of the Frequency of Transient Lunar Phenomena with Routine Observations

In a previous study we found that Transient Lunar Phenomena (TLP) are more frequent at the end of April than at other times of the year and that TLP appeared to be more prevalent around local lunar sunrise. By normalizing the TLP data against a new database of routine non-TLP observations, and assigning weights to observations, we now show that neither effect is apparent, although an increase towards local noon appears present in the local time of day analysis.
