“…Therefore, the comet is expected to be active again in March 2014 before the arrival of Rosetta (Snodgrass et al 2013), which is in line with our predictions presented above. Analysis of previous observations also indicates that the peak of activity takes place about two months after perihelion (de Almeida et al 2009). …”

“…The International Rosetta Mission was approved in 1993 and has been developed by the European Space Agency (ESA). Since its approval, several works have been published studying the target of this cometary mission using both ground and space-based observations with special interest on the evolution of the activity during its orbit (e.g., Kelley et al 2009;de Almeida et al 2009;Snodgrass et al 2013). Rosetta was launched in March 2004 and will arrive at comet 67P/Churyumov-Gerasimenko (a short-period comet with P = 6.45 yrs) in July 2014 at ∼3.8 AU from the Sun.…”

“…Our dataset allows us to derive a (most likely relative) maximum dust activity, determined through Afρ takes place on March 12, that is, 12 days after perihelion. From an exhaustive analysis of the reported observations during 1982, 1996and 2002(Osip et al 1992Weiler et al 2004;Lara et al 2005;Schleicher 2006), de Almeida et al (2009 note that 67P/C-G displays an asymmetry in water (or gas) release rates close to perihelion with peak productivity about two months after perihelion. Unfortunately, we monitored the comet until March 19, barely 3 weeks after perihelion, so we cannot confirm that the comet indeed peaks activity two months after the 2009 perihelion on February 28.…”

“…Ablation occurs when ice is exposed on the surface of the nucleus and thus, naturally, the ice production rate is enhanced. These new models, denoted Ablt-A and Ablt-B, yield a total water production rate that exceeds the observationally inferred rate (Crovisier et al, 2002;de Almeida et al, 2009) by almost an order of magnitude, as shown in Fig. 8.…”
