Chris Samuel<p>Boo, I had been waiting for Comet C/2025 F2 (Swan) to come into the evening sky in late April; on 1st May it was going to be near the Pleiades and I thought it could make a nice picture.</p><p>But sadly from the reports on the comets-ml mailing list over the last few days it appears this is very its last time around the sun (period ~30k-80k years); it looks very much like its nucleus has disintegrated. 😞 <a href="https://mastodon.acm.org/tags/comet" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>comet</span></a> <a href="https://mastodon.acm.org/tags/astronomy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>astronomy</span></a></p>

Daniel Fischer<p>The visibility conditions for comet C/2025 F2 (SWAN) through perihelion and maximum brightness for 51.5° North - see <a href="https://www.facebook.com/dan.fischer.393/posts/pfbid023poyxvFZYhxPsT18sxHZejFPYYGiXdeApa3dj78oPqmnw8QRLH22dVFCABnLk93Zl" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">facebook.com/dan.fischer.393/p</span><span class="invisible">osts/pfbid023poyxvFZYhxPsT18sxHZejFPYYGiXdeApa3dj78oPqmnw8QRLH22dVFCABnLk93Zl</span></a> for explanations of the table! In a nutshell, in Central Europe the comet is higher at a given degree of sky darkness in the morning until about 23 April, then in the evening. So expect it at 3 to 5 mag. low at dusk: if the <a href="https://scicomm.xyz/tags/comet" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>comet</span></a> makes it and keeps its fine tail this *may* become a fine nightscape photo opp - but not a significant show for the naked eye.</p>
