Problem:Cyanobacteria / saɪˌænoʊbækˈtɪəriə /, also known as Cyanophyta, is a phylum of bacteria that obtain their energy through photosynthesis, and are the only photosynthetic prokaryotes able to produce oxygen.

Student A:There is an average of forty-five inches of rain a year (fifty in the mountains). July storms account for much of this precipitation. As much as 15 % of the rainfall during the warm season in the Carolinas can be attributed to tropical cyclones. Mountains usually see some snow in the fall and winter. Moist winds from the southwest drop an average of 80 inches (2,000 mm) of precipitation on the western side of the mountains, while the northeast-facing slopes average less than half that amount.

Problem:Early on December 15, the system crossed west of 135 ° E and entered the Philippine Atmospheric, Geophysical and Astronomical Services Administration's (PAGASA) area of responsibility. Upon doing so, PAGASA began issuing advisories and assigned the cyclone with the local name Sendong. Shortly thereafter, the storm passed close to or over Palau. By 0600 UTC, the JMA upgraded the system to tropical storm status, at which time they assigned it with the name Washi. Maintaining a rapid westward track, Washi slowly became more organized, with low-level inflow improving during the latter part of December 15. On December 16, Washi reached its peak strength as a severe tropical storm and made its first landfall along the east coast of Mindanao.

Answer this question based on the passage: when did sendong enter the philippine area of responsibility?
Solution:OK... This is the relevant information: Early on December 15, the system crossed west of 135 ° E and entered the Philippine Atmospheric, Geophysical and Astronomical Services Administration's (PAGASA) area of responsibility.
